SSU Program Updates

July 26, 2010

Professor Lynn Cominsky


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.


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.


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’s 500 Bursts


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


“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


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

The UVOT saw nothing unusual.

  • 6/21/10: XMM-Newton line detection provides new tool to probe extreme gravity

  • 5/31/10: Novel observing mode on XMM-Newton opens new perspectives on galaxy clusters

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


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 1015 solar masses,

    • a temperature of about 9.3 keV

    • redshift z=0.32

  • Needs multi-wavelength approach to detect and measure distant clusters


Latest XMM News:

  • 4/30/10: Jets from BHs expel gas not only from their host galaxies but even from the space between galaxies in groups

Blue is radio jet

Red is X-ray emitting gas
