SSU Program Updates July 26, 2010 Professor Lynn Cominsky
2
Current SSU Missions Fermi (formerly GLAST) - launched June 11, 2008 – nominal mission is 5 years – Project Scientist Julie McEnery will update Swift – launched November 20, 2004 XMM-Newton – launched December, 1999 NuSTAR – now in Phase C/D, planned for Feb. 2012 launch SNAP – reconsituted as JDEM = Joint Dark Energy Mission. In limbo pending “Blandford committee” report EXIST – also in limbo…

Changes in the EA program Fermi EAs have resigned: Walter Glogowski, Sharla Dowding Fermi EA has had a baby – Janet Moore – cannot be with us this week Linda Smith, Fermi EA is in Master’s program at Penn which will not let her attend training week David Beier has had some health problems recently and is under Dr’s order not to fly NuSTAR EA Bill Panczner has had serious surgery and has had to retire. Tyson Harty (Georgia) is with us this week to see if he will join the program.
4
Senior Review Results 2010 Happens every 2 years – determines funding for next 2-4 years. Fermi was not reviewed – it is in its 5-year nominal mission. It will be up for review in 2012 cycle.

Swift and the Sr. Review Swift was #1 in the 2008 senior review. However, it still did well in this review: “Swift was launched on November 30, 2004 and is presently operating well. There are no known issues that would prevent operation for many more years.” “Swift is a productive and important mission making significant contributions to astronomy. The Swift Guest Investigator program is producing very good science and should continue to be a key component of the mission.” Funding was recommended at the expected level through 2012, with reassessment for 2013-2014. I expect to receive sufficient Swift E/PO funds for at least two more years, to continue to fund the 5 Swift EAs. And probably for four more years.

XMM and the Sr. Review XMM was rated #8/10 in 2008. It did much better this year. “XMM-Newton, launched in 1999, is a facility- class X-ray observatory that is a cornerstone of ESA’s Horizon 2000 program. It retains strong European support, and in the most recent review of extended ESA missions it was among the most highly rated. After a decade of operation, the spacecraft health and performance remain satisfactory” Because XMM was rated so low in 2008, it came into the Sr. Review with a very low “in-guide” number. Therefore, they asked for an augmentation for 2011- 2014. This was approved for 2011, with more for 2012, and another review for 2013-2014. I am waiting to see how this translates into money for E/PO. I will probably know by the Fall.
7
EA Shuffle…. So if XMM funding is seriously cut, the two XMM EAs will switch over to being funded by Fermi, which is now 2 EAs short. But we won’t know until Fall. Also, travel money seems to be at a premium since so many people are overrunning. I can’t afford to keep the stipends the same, and also raise the travel funding. Last time we raised both…. Let’s discuss.

New SSU Project(s) Funding received for development of an on-line general education Cosmology course for undergraduates – in progress. We will have a short presentation by Geraldine Cochran, who has been doing education research with Prof. Kim Coble about students’ views in Cosmology SSU is trying to get funding for other projects – High School CanSat and high-powered rocket curriculum development, Palomar Observatory museum exhibit to augment NuSTAR E/PO program, and (at least one) potential new Explorer satellite. Results for the first two should be announced in the late Fall 2010.

Swift Swift continues to enjoy good health, has recently detected 500 th burst. Swift is now a mature mission, and although its primary science is still GRBs, there are many other exciting things that Swift is studying… –Supernovae –Active Galaxies –Other flares

Swift’s 500 Bursts
16
Most distant burst (again) April 23, 2009 – redshift 8.2 or 630 million years after the BB So far away that the optical afterglow was redshifted into infrared Previous record holder GRB080913 had z=6.7, was 190 million light years closer
17
“Naked Eye” Burst = GRB080319B Afterglow so bright it could have been seen by someone’s unaided eye (if they had been looking) Jet must have been aimed right at Earth, with particles traveling at 99.99995% c
18
The burst that “blinded” Swift GRB100621A – so bright in x- rays that the XRT was saturated Not noticed until UK astronomer Phil Evans returned from vacation and data were missing from this burst He reconstructed the burst to determine that this was the brightest x-ray source ever seen by Swift – 143,000 x-ray photons per second! Distance to burst was about 5 billion light years XRT image shown in red to yellow colors. The UVOT saw nothing unusual.

21
Sunyaev-Zel’dovich Effect Photons from cosmic microwave background travel through clusters of galaxies on their way to our detectors The electrons in the ionized (X-ray emitting) gas in the clusters interact with the CMB photons, modifying their spectrum in a special way – this is the “Sunyaev-Zel’dovich effect” The modified CMB spectrum can be measured by mm-wavelength telescopes
22
XMM detections of galaxy clusters Microwave contours in white X-ray emitting gas: purple Overlaid on optical image The cluster has a mass of over 10 15 solar masses, –a temperature of about 9.3 keV –redshift z=0.32 Needs multi-wavelength approach to detect and measure distant clusters
