2. View from the Chair - Chryssa Kouveliotou

This year I took over the HEAD chair from Mitch Begelman -- a usually uneventful duty and a pleasant one at that. In 2010, however, there is a lot to be concerned about, the global financial crisis notwithstanding. Of particular interest to our community is the upcoming report from Astro2010, the current Astrophysics Decadal survey, that has gone beyond any other survey in its efforts to collect accurate and thorough information on all existing and currently developed assets and technology in Astrophysics, together with extensive studies in the "social culture" of the field in the States and internationally. At the same time, however, the NASA Astrophysics budget for new missions is dramatically reduced. As a result, very few of these Astro2010 prioritized missions would be built, should the budget remain unchanged.

And yet the HEAD membership has grown and for the first time is close to reaching the 1000 member milestone. Our recent -- 11th -- HEAD meeting on the Big Island of Hawaii reached an unprecedented participant level of 522 attendees! And most importantly (for me at least) about 30% of the participants were women and a good percentage was young HEAD members. So, we are growing, we are interested and we have heritage and continuity. We are now in the golden years of HEA with about fifteen active missions. In ten years, this number is projected to be 1 or 2. It is very important, therefore, to stress here that the precious few new missions given highest priority by Astro2010 will take all the support we can provide to materialize. Let me be clear: I am not happy with the frugal reality of our field and as a private citizen, I advocate more funding for Astrophysics. I consider, however, the strong support of the Decadal report as an important first step in building on our future. So it will take your active interest, cooperation and participation in the process to make it happen. The HEAD Executive committee will be the link between the community and the Decadal -- we will send frequent newsletters and updates as soon as the report is public, on the different ways you can help. We need you to be active and we need your input on how to be successful and resourceful.

I take the opportunity here to stress one more issue that concerns me greatly. In the past several years, we have been struggling to obtain nominations for our Division's highest award, the Rossi Prize. I can hardly believe that in almost 1000 members we cannot find at least 10 candidates with excellent qualifications every year! Please, do not depend on your "neighbors" for the nomination -- be the one who is active. An honorable award is all that many of us strive for these days; we did not get into the field for the money...

And stay tuned for the upcoming Decadal activities. Even, or especially with the current budget, we need a unified community solidly behind the Decadal. To quote the Greek poet, Kavafis: "...And if you find her poor, Ithaka won't have fooled you. Wise as you will have become, so full of experience, you will have understood by then what these Ithakas mean."

3. Congressional Visits Day Summary - Paul Ray (HEAD EC Member)

On April 28-29, hundreds of scientists and engineers flocked to Capitol Hill as part of Science, Engineering and Technology Congressional Visits Day. We spent the first day getting briefed on the legislative and budgetary processes and hearing updates from NSF (Jim Ulvested) and NASA (Ed Weiler). The message we heard was that there is a lot of support for continuing on the path to double basic research funding over a 10 year period at several agencies (NSF, DOE, NIST) under the America COMPETES Act. Note that NASA is not included in this Act, but their budget is scheduled to grow by $6 billion over the next 5 years as part of the President's new approach to space exploration and discovery. This rising tide is very good for science as a whole; however, the situation for astronomy and astrophysics is not so good. At NASA this is because the President's priorities are earth science and climate change, while at NSF, even the most optimistic funding scenarios still see the costs to build and operate large new facilities forcing hard decisions on operations of current instruments and the funding of research grants. So, the message we carried to congress was that astronomy should be viewed as a crucial part of the nation's science and technology research agenda that should specifically be included in efforts to grow basic research. We emphasized that astronomy is a "gateway science" that inspires the public and is the only college-level science class for a very large number of people. We asked each member to support the re-authorization of COMPETES.

We thank Anita Krishnamurthy (AAS Bahcall Public Policy Fellow) and Kevin Marvel (AAS Executive Officer) for organizing this important effort. Photos of the AAS contingent are posted at http://picasaweb.google.com/American.Astronomical.Society/CVD2010. Although I was the only HEAD representative at this event, we will get another opportunity to participate in greater numbers when we visit congress in the Fall on the heels of the release of the Astro2010 Decadal Survey report. And, as always, we strongly encourage all HEAD members to personally appeal to the political leadership, at the state and national level, with the positive message that astronomy and astrophysics engages public (especially student) interest in science, has strong societal impact, including e.g. the creation of high technology jobs, and is therefore worthy of support and inclusion in the competitiveness and recovery agendas. Personal letters and visits from constituents carry a great deal of weight!

5. HEAD in the News - Megan Watzke (HEAD Press Secretary) and Lynn Cominsky

The realm of high-energy astrophysics continues to produce interesting and newsworthy results. The list below contains some of the major stories to come out of the fleet of operating missions as press releases and press conferences in the past six months, but it does not represent the full scope of how astronomical results are communicated with the public. In this age of blogs, podcasts, and smart phones, the latest scientific results are being shared in ever-changing ways. For a more comprehensive view of this is being done, visit the respective websites of each of the missions.

CHANDRA NEWS

FERMI NEWS

  • "NASA's Fermi Probes "Dragons" of the Gamma-ray Sky" March 2, 2010 A study showed that less than a third of the gamma-ray background can be explained by AGN. http://www.nasa.gov/mission_pages/GLAST/news/gamma-ray-dragons.html This was a press conference at the HEAD meeting in Hawaii.
  • "NASA's Fermi Closes on Source of Cosmic Rays" Feb 16th, 2010 By comparing emissions from supernova remnants of wildly differing ages and in different interstellar environments, astronomers have gained more evidence that cosmic rays originate from supernova remnants. http://www.nasa.gov/mission_pages/GLAST/news/cosmic-rays-source.html This was a press conference at APS meeting in DC.
  • "Nature's Clocks May Make ‘Galactic GPS' Possible" Jan 5th, 2010 With Fermi helping to discover 17 millisecond pulsars in our galaxy within three months, astronomers are closer to being able to use the radiation of these rapidly spinning neutron stars as a kind of GPS to detect and track gravitational waves. http://www.nasa.gov/mission_pages/GLAST/news/galactic-gps.html This was a press conference at AAS meeting in DC.
  • "Fermi Sees Brightest-Ever Blazar Flare" Dec 8th, 2009 A galaxy with the unassuming name of 3C 454.3, has become the brightest source of gamma rays in the sky despite being over 7 billion light years away. The flares began on September 15, 2009 and Fermi has been watching ever since. For the original press release: http://www.nasa.gov/mission_pages/GLAST/news/brightest-blazar.html
  • "Fermi Telescope Peers Deep Into Microquasar" Nov 26th 2009 First Discovered in 1966, Cygnus X-3 has long been suspected of being a high-energy gamma-ray emitter which Fermi confirmed from observations made earlier this year and late last year. This data also revealed that the gamma-ray emissions precede the microquasar's radio jet flares by approximately five days. For the original press release: http://www.nasa.gov/mission_pages/GLAST/news/fermi-cygnus.html
  • "Fermi Detects Gamma-Rays From Distant ‘Star Factories'" Nov 2nd 2009 Fermi has detected diffuse gamma-ray emissions from starburst galaxies with implications that it is the stellar nurseries producing the gamma rays. For the original press release: http://www.nasa.gov/mission_pages/GLAST/news/star_factories.html

SWIFT NEWS

  • "NASA's Swift Catches 500th Gamma-ray Burst" Apr 19th, 2010 Swift detected its 500th gamma-ray burst (GRB) on April 13, 2009. Known as GRB 100413B, this GRB was located in constellation Cassiopeia and was a long burst, such as those caused by the end of the life of a high-mass star. http://www.nasa.gov/mission_pages/swift/bursts/500th.html
  • "Magnetic Power Revealed in Gamma-Ray Burst Jet" Dec 9th, 2009 Swift's detection and notification of a gamma-ray burst (GRB) on January 2, 2009, allowed Liverpool John Moores University's optical polarimeter, RINGO, to measure the magnetic fields of the GRB. http://www.nasa.gov/mission_pages/swift/bursts/magnetic-power.html
  • "Swift XMM-Newton Satellites Tune Into a Middleweight Black Hole" Nov 10th, 2009 By turning Swift and XMM-Newton to ultraluminous X-ray sources (ULXs), astronomers have found strong candidates for intermediate-mass black holes. For one such ULX, NGC 5408 X-1, astronomers have detected quasi-periodic oscillations akin to stellar mass black holes but far brighter, and have estimated the object to be between one and nine thousand solar masses. http://www.nasa.gov/topics/universe/features/middle_blackhole.html

6. Chandra X-ray Observatory Report - Roger Brissenden (SAO) and Martin Weisskopf (MSFC)

Chandra has now carried out almost 11 years of successful science operations, with excellent performance by the spacecraft, instruments, and mirror assembly.

Following an extensive proposal process, NASA, in December, signed a contract modification extending Chandra operations through September 2013, with two additional three-year options to 2016 and 2019. NASA also conducted its biannual Senior Review of operating missions. The panel rated Chandra second of eleven missions, with a score of 9.5 out of 10. The panel observed, "After a decade in operation, Chandra remains an immensely powerful observatory in its prime....Chandra has subarcsecond spatial resolution with spatially resolved spectra on the same scale. These attributes do not exist in any other mission and will not be seen again for several decades."

We have taken several steps to make mission operations more robust and flexible, including updating ACIS flight software, testing the momentum unloading thrusters at elevated temperatures, and improving the ground spacecraft simulator. Chandra's overall observing efficiency has remained close to optimal. The science data processing, archiving, and distribution proceeded smoothly, with time from observation to data release remaining at about a day.

The Einstein Fellowship program attracted a record 162 proposals for 10 fellowships, whose recipients were selected in January by a panel with expertise covering NASA's entire Physics of the Cosmos program.

Researchers worldwide submitted 678 proposals in response to the Chandra X-ray Center's Call for Proposals for observing Cycle 12. The Peer Review will be held in June.

The CXC will conduct the workshop "Accretion Processes in X-rays: >From White Dwarfs to Quasars" on 13-15 July in Cambridge, MA.

The Chandra Press Office issued 14 press releases and 21 image releases in the period November through May. A complete listing is available at http://chandra.harvard.edu/press/.

7. XMM-Newton Mission News - Lynne Valencic and Lynn Cominsky

The Ninth Call for Proposals for XMM-Newton closed in October 2009; successful submissions were announced in December 2010, and observations began in May 2010.

The XMM-Newton Science Operations Centre has organized a workshop for May 24-26 on Ultra-Luminous X-ray Sources and Middle Weight Black Holes in Madrid, Spain. The goal of the workshop is to explore the physical nature of ultra-luminous X-ray sources and models for their formation, accretion, and evolution. More information, including the submitted abstracts, can be found here: http://xmm.esac.esa.int/external/xmm_science/ workshops/2010_science/.

The fifth International Astronomical Consortium for High Energy Calibration (IACHEC) meeting took place in Woods Hole, Massachusetts during April 12-15. Updates on the XMM-Newton's instrument calibrations and comparisons with Chandra's instruments were discussed; the presentations are available in pdf format at http://web.mit.edu/iachec/meetings/2010/index.html.

On the EPO side of things, work continues on the eXtreme Universe planetarium show, to be hosted by the NASA Goddard Geodome. XMM-Newton co-sponsored a teacher's workshop in Hawaii after the HEAD meeting, with activities from the Supernova guide. XMM-Newton was featured in the May Special Episode of Epo's Chronicles, which will appear as part of the 2011 Epo's Chronicle Calendar.

8. RHESSI Mission News

The Reuven Ramaty High Energy Spectroscopic Imager (RHESSI) has just completed a successful second anneal of its high-resolution germanium detectors to reduce the effects of radiation damage. RHESSI's overall solar hard x-ray performance is now even better than when it was newly launched. Because there is some residual damage, the resolution for nuclear gamma-ray lines is still degraded, but the instrument is in good condition for continuum spectroscopy of non-solar sources like cosmic gamma-ray bursts and terrestrial gamma-ray flashes. See RHESSI Science Nugget #127 at http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets where you can also find short articles on a variety of RHESSI science topics.

9. INTEGRAL Mission News - Christoph Winkler (ESA-ESTEC) and Steve Sturner (NASA GSFC)

The INTEGRAL mission is currently approved by ESA for science operations until 31 December 2012. A request for extension of mission operations until 31 December 2014 will be submitted later this year to ESA' advisory committees.

The AO-7 observing cycle will continue until 31 December 2010. The Call for AO-8 cycle observations was released on 15 March. By the deadline of 23 April, 64 proposals were received, oversubscribing the available observing time by a factor 3.8. Results of the time allocation peer review process will be announced in June. The second Call of the AO-8 cycle, this time for data rights only for sources located in the FOV of selected AO-8 observations will be released on 30 August, with a deadline of 08 October. As with previous INTEGRAL AO cycles, NASA will fund US scientists with successful AO-8 proposals via the NASA INTEGRAL Guest Investigator Program.

The US INTEGRAL project recently participated in the 2010 NASA Senior Review. A proposal was submitted with extensive input from the US INTEGRAL Users' Committee. Oral presentations were given to the Senior Review Committee by Dr. Neil Gehrels, the US Project Scientist, and Dr. Mark Leising, the chair of the users' committee. The recommendation of the Senior Review Committee to NASA was to discontinue funding for the INTEGRAL project in the US including funding for the US INTEGRAL GOF and the US Guest Observer Program. The US mirror to the INTEGRAL Public Data Archive will be maintained as part of the HEASARC.

The 8th INTEGRAL workshop, "The restless gamma-ray universe" will take place 27-30 Sep 2010 in Dublin/Ireland , see the LOC website http://ssmr.ucd.ie/8thintegralworkshop/INTEGRAL_Workshop/8th_INTEGRAL_Workshop.html for further details.

Some recent scientific highlights since the last report (November 2009) include:

  • First constraints on the hard X-ray morphology of the Crab nebula (D. Eckert et al, A&A 509, 33, 2010)
  • The Fermi/LAT Sky as Seen by INTEGRAL/IBIS (P. Ubertini et al., 2009, ApJL 706, L7-L11, 2009)
  • The Magellanic Bridge: evidence for a population of X-ray binaries (V.A. McBride, et al., 2010, MNRAS in press, arXiv: 0912.2951)
  • New estimates of the gamma-ray line emission of the Cygnus region (P. Martin et al., A&A 506, 703, 2009),
  • Predicted gamma-ray line emission from the Cygnus complex (P. Martin et al., A&A 511, 86, 2010)
  • Improved X-ray position for unidentified/unclassified INTEGRAL sources in the 4th IBIS survey (J.B. Stephen et al., 2010, ATEL 2441)

10. Swift Mission News - Stefan Immler (UMd/GSFC), Lynn Cominsky (Sonoma State), & Neil Gehrels (GSFC)

Senior Review Results

Swift was ranked #4 (after Planck, Chandra and Spitzer) in the 2010 Senior Review of NASA's Astrophysics Division operating missions. The high ranking and excellent health status of Swift will allow operations through 2012 with an extension through 2014 pending review in two years. The Senior Review Committee also recommended that the Swift Guest Investigator program should continue to be a key component of the mission.

Swift Catches 500th Burst

On April 13, Swift detected its 500th Gamma-Ray Burst (GRB). This "500 bursts in 5 years" milestone added to a long series of Swift's accomplishments, such as discovering the highest spectroscopically confirmed object in the universe (GRB 090423 at z=8.2), recording a "naked eye" burst (GRB 080319B), and witnessing the birth of a supernova (SN 2008D). To date, 75% of all GRBs with known redshifts were discovered by Swift.

Swift X-Ray Survey finds dozens of new AGN

In a recent Swift BAT study published in ApJL, Mike Koss et al. find that roughly 22% of Swift-observed AGN undergo mergers. Since surveys in other wavelengths find significantly fewer AGN in mergers because of extinction and dilution by star formation, the Swift BAT hard X-ray survey is a statistically complete survey of AGN in the nearby universe (z<0.05).

Swift E/PO News

The Educator Ambassadors representing the Swift mission have continued to present teacher workshops focusing on the telescope, its science, and using Swift materials like the Gamma Ray Burst Educator Unit. Swift has supported the From Earth to the Universe exhibit around the bay area, which has continued on into 2010. The 2010 February Special "Eposode" for Epo's Chronicles featured Swift and will be included in the 2011 Epo's Chronicles Calendar.

11. Suzaku Mission News - Koji Mukai (NASA GSFC)

In the 2010 NASA Senior Review of operating missions, Suzaku was ranked 7th out of 11 missions under consideration. More importantly, the Senior Review panel recommended the continued US participation in this mission through FY2014, including a modest level of guest observer funding. We thank the Suzaku Users' Group, led by the chair, Jon Miller of University of Michigan, as well as the wider Suzaku user community, who made it possible to submit a strong proposal to the Senior Review.

The Suzaku satellite and its instruments continue to perform well in general, with the following minor issues. Of the 3 operational X-ray Imaging Spectrometers, XIS1 has developed a bright and persistent spot during day-earth (but not night-earth) observations on 2009 December 18, presumably due to a pin hole in the optical blocking filter. This does not impact most science observations, although those of low surface brightness, soft diffuse emission may be affected. The details are under study. As for the Hard X-ray Detector, the continued increase of noise events, due to the accumulation of radiation damage, has forced the HXD team to raise the low-energy threshold of the PIN detector three times in the recent months (on 2010 January 17, February 1, and April 3). These changes define new "epochs", 7-9. Although all observations are processed appropriately, response matrices are different for different epochs, and it is the user's responsibility to select the correct one. Response files for epochs 7-9 will be released within the next several months.

The HXD team has updated the gain calibration of the GSO detector and released updated software, new calibration files, and a new set of background files. With this update, GSO data are better calibrated in general, and in the 50-70 keV range in particular. For more details, see http://heasarc.gsfc.nasa.gov/docs/suzaku/analysis/gso_newgain.html.

The GOF has released version 3.2 of the data reduction guide, bringing it up to date except that it does not fully reflect the new GSO calibration. We plan another update of the guide, once we have accumulated sufficient experiences processing and analyzing the newly recalibrated GSO data.

Observations of AO-5 targets began at the end of March. The target list includes the continuation of 4 Key Projects initiated in AO-4 (3 of them to completion), as well as one new Key Project, on the outskirts of the Perseus cluster of galaxies. The Stage 2 (budget) proposals from PIs of successful US AO-5 proposals have been received by NASA, and the decision is expected in a couple of months. The actual funding will begin sometime early in the next fiscal year that begins on 2010 October 1.

12. Fermi Mission News - Julie McEnery (GSFC), Chris Shrader (GSFC), Dave Thompson (GSFC), Liz Hays (GSFC) & Lynn Cominsky (Sonoma State)

The first Fermi LAT catalog (1FGL) contains 1451 sources, by far the largest catalog of high-energy gamma-ray sources yet produced. The catalog, released in January 2010, is available through the Fermi Science Support Center, at http://fermi.gsfc.nasa.gov/ssc/data/access/lat/1yr_catalog/. About half the sources are associated positionally, mostly with blazers (~600) and pulsars (~60), many additional smaller classes of high energy gamma-ray emitters are emerging – globular clusters, pulsar wind nebulae, supernova remnants, starbursts, narrow line Seyferts and X-ray binaries with several being new to high energy gamma-ray astrophysics. Intriguingly, the second-largest set is sources having no obvious associations with members of known gamma-ray source classes, showing the potential for future discoveries.

We triggered our first Fermi TOO at the beginning of April to get deeper observations of 3C454.3 which had flared brightly. The target region received a factor of 3-4 increase in exposure, with a penalty that a large region of the sky received no exposure.

The LAT team made a significant update to the configuration of their onboard transient search software. This is expected to more than double the rate of prompt detections of LAT gamma-ray bursts and will provide rapid localizations of these bursts (0.1-0.5 deg) to the community via GCN.

The GBM team added a new onboard trigger tuned to finding Terrestrial Gamma-ray Flashes -- intense millisecond flashes of gamma-rays and high energy particles from thunderstorms.

Fermi Guest Investigator Program

The Fermi Cycle 3 Guest Investigator (GI) program attracted nearly 200 proposals. The stage-I scientific evaluation process has been completed, leading to the selection of 77 new guest investigations. Results have been announced at http://fermi.gsfc.nasa.gov/ssc/proposals/cycle3/AcceptedPrograms.pdf.

Data and Software Releases

Flaring activity from LAT sources has been announced through 80 Astronomer's Telegrams (ATels) since the beginning of the mission. Weekly (http://fermisky.blogspot.com/) and daily (http://fermisky-daily.blogspot.com/) blogs describe current activity in the gamma-ray sky.

The GBM team has released a software package for the analysis of GBM data on GRBs and other transients. The RMFIT tool will create lightcurves, fit backgrounds, and fit single or multiple spectra for NaI and BGO detectors. It also provides burst fluences and spectral evolution visualization tools, and has a number of additional useful capabilities. While RMFIT is not a part of the standard Science Tools package, you can find it on the user-contributed software page at: http://fermi.gsfc.nasa.gov/ssc/data/analysis/user/ In addition, the GBM team has provided a very useful tutorial at http://fermi.gsfc.nasa.gov/ssc/data/analysis/user/vc_rmfit_tutorial.pdf

The Third Fermi Symposium

This will be held in Rome, Italy from May 9-12. Further information will be posted to the symposium webpage: http://fermi.gsfc.nasa.gov/science/symposium/2011/

Fermi E/PO News

Fermi has been highlighted in Epo's Chronicles 2010 Special Episodes for March, and will be a part of the 2011 Epo's Chronicles Calendar. (http://eposchronicles.org) The Fermi Race Card Game has recently been showcased at the Northern California Boy Scouts of America Centennial Anniversary Jamboree and Expanding Your Horizons (for eighth grade girls).

13. NuSTAR Mission News - Daniel Stern (JPL) & Fiona Harrison (Caltech)

NuSTAR, the Nuclear Spectroscopic Telescope Array, is a NASA Small Explorer (SMEX) mission which will provide the first focused observations in the 6 to 79 keV hard X-ray window. In part due to launch scheduling conflicts with larger missions such as MSL, Juno, and GRAIL, the NuSTAR launch was recently moved to February 2012.

Significant flight hardware is now being built. NuSTAR will fly two optical units, each with 133 layers of grazing incidence optics. Goddard has completed slumping all glass segments out thru layer 90, with the final glass slumping to be completed in late October. The multilayer coating recipe has been finalized and flight optics coating is on schedule at the Danish Technical University, DTU-Space in Copenhagen, Denmark. The first optical unit, being assembled at Columbia University, is more than 65% complete and will be finished at the end of July. The final optic will be completed in early January 2011.

14. The International X-ray Observatory (IXO) - Michael Garcia (CfA)

There was an IXO Science meeting in Paris at the end of April. The presentations from the meeting can be found at: http://ixo.gsfc.nasa.gov/resources/IXOParisApril2010.html The main topics of the meeting were recent results and preparations for the ESA Cosmic Visions 2015-2025 (CV2015) process, with an emphasis on synergies between IXO and other future observatories. The science, technology and programmatic input is collected into a 'Yellow Book' which is the submission to the CV2015 process. The science section draws from the white papers and 'Requests for Information' (RFIs) that were written for the Astro2010 process, and also includes new information. This section is in draft form and will continue to be developed over the next few months. The technology section will be based largely on the two parallel industry studies that ESA is currently carrying out. Final report from the CV2015-2025 process is expected about June 2011.

Upcoming events include a series of IXO presentations at the SPIE meeting, 'Astronomical Telescopes and Instrumentation 2010' which will take place in San Diego the end of June 2010. Talks will cover the overall observatory, instrumentation (including the expected background), optics, mission operations, and other topics. As usual, these talks will be available on the IXO website ixo.gsfc.nasa.gov

Technology development efforts are continuing, with progress on both optics technologies (slumped glass and silicon pore optics). X-ray pencil beam tests of the SPO optics are now finding 9'' HEW/PSF (two reflections) for small stacks of plates mounted in a flight-like mirror module. As a reference, in 2007 similar tests measured 17'' HEW/PSF. Upgrades to the Bessy-II and MPE/Panter X-ray test facilities are underway to accommodate the 20m focal length of the IXO optics, and will allow full beam test in the fall of 2010. X-ray test of the slumped glass optics found 16'' HEW/PSF in 2008, and optical metrology is now measuring 6.5'' HEW/PSF. These optics will be tested in the GSFC X-ray test facility before the end of 2010. A separate study of slumped glass optics is underway at MPE (Germany) and Brera (Italy) which would use connecting/reinforcing ribs to assemble mirror modules, similar to the NuStar method. The IXO Telescope Working Group will hold its next meetings in June (Brera) and December (Prague)to assess progress and to review and update the technology development plans for both types of optics. The XMS team is fabricating 32x32 pixel demo arrays, with the correct pitch and close to the 40x40 extent needed for the inner high resolution array for the XMS. Preparations are continuing for a 3-column x 32-row multiplexing readout demonstration of such an array.

15. LISA News - Michele Vallisneri (JPL)

LISA Pathfinder, the second of the European Space Agency's Small Missions for Advanced Research in Technology (SMART), is a dedicated technology demonstrator for LISA. LISA Pathfinder will test the critical technologies required for the detection of low-frequency gravitational waves from space; it will carry two payloads, the European-provided LISA Technology Package, and the NASA/JPL Disturbance Reduction System. The LISA Pathfinder project is well into Phase C/D, having successfully passed Critical Design Reviews for both the payload and system. At this time, most flight-hardware units have been delivered, and system testing is underway for the payload and the drag-free and attitude control system, using the real-time hardware-in-the-loop testbed. The integrated-systems testing of the spacecraft bus has also begun. Tests will continue over the next two years, with launch scheduled for mid 2012 onboard the new European small launcher, VEGA.

Non-thermal phenomena in colliding galaxy clusters
15-18 November 2010
Nice, France
Contact: C. Ferrari, chiara.ferrari@oca.eu
http://cassiopee.oca.eu/spip.php?article323

The workshop will address a wide range of phenomena related to non-thermal particles and magnetic fields in and around galaxy clusters. These sites provide a unique laboratory for studying the physics of dilute plasmas. Recent years have seen rapid progress in this field, as radio, X-ray and gamma-ray telescopes are providing unprecedented new details and constraints on the properties of the intracluster relativistic plasma and its interplay with the thermal medium.

The nature and origin of non-thermal particles and magnetic fields in cosmological large-scale structures are still not fully understood. The most spectacular non-thermal phenomena appear to be related to collisions between galaxy clusters that free enormous amounts of energy. Addressing this connection is one of the main goals of the workshop. Other topics will include non-thermal components in more relaxed clusters and large-scale filaments. We will also discuss recent progress in theoretical and numerical work that attempts to model the origin and evolution of relativistic particles and magnetic fields.

The workshop will bring together observers and theorists in order to develop the latest ideas and models for the cluster non-thermal components, and to devise strategies for future observations with the next generation of telescopes, such as the Low-frequency Array (LOFAR), which will be conducting its first observations. The workshop will help to foster collaborations and introduce young scientists to the community.

On-line registration is not yet available. Please visit the conference web page soon. Due to venue constraints, we have to limit the number of participants at 70.
