First Gamma Sky Map from GLAST—Now the Fermi Gamma-ray Space TelescopeThe Department of Energy and NASA yesterday presented the first all-sky maps from the Gamma-ray Large Area Space Telescope. In the morning press conference, project leaders also announced that the observatory would now take the name Fermi Gamma-ray Space Telescope in honor of high-energy physics pioneer and Nobel laureate Enrico Fermi. For two months following the mission's June 11, 2008 launch, scientists tested and calibrated its two instruments, the Large Area Telescope and the GLAST Burst Monitor. "What impressed me the most is that everything went by the book," said Peter Michelson, LAT principal investigator at Stanford University. "We're elated." The LAT has already verified sources found by other gamma-ray detectors—and discovered more. The all-sky image from the onboard Large Area Telescope shows the glowing gas of the Milky Way, blinking pulsars and a flaring galaxy billions of light-years away. The map was created using only 95 hours of "first light" observations, compared with past missions that took more than a year to produce similar images. SLAC played a key role in assembling the instrument and now plays the central role in LAT science operations, data processing and making scientific data available to collaborators for analysis. The NASA mission was made possible by collaboration with many U.S. and international partners. "The DOE-NASA collaboration on this new observatory has been very successful and shows what can be accomplished when we work together," said Dennis Kovar, DOE Associate Director of Science for High Energy Physics. "We look forward to the scientific discoveries it will enable in both particle physics and astrophysics." Read more in the full DOE press release and NASA mission Web site. |

SULI Students 2008The Summer Undergraduate Laboratory Internship program officially wrapped up last week, and its bright young students headed back to their home institutions. The summer was full of hard work, but also fun, excitement and new friendships. For nine weeks, SULI participants worked alongside their SLAC mentors in areas including astrophysics, accelerator science, synchrotron science, social science, and science writing. The students concluded the summer with talks and papers outlining their summer research. "My summer was filled with meeting awesome people and writing an awesomely efficient code for simulating reionization," quipped SULI student Shuenn Patrick Ho. "My favorite part about SULI was not only being a part of a successful project, but also seeing how I could do it in a fun place and a comfortable environment. SLAC rocks!" Ho attends Princeton University and did astrophysics simulations of ionized hydrogen bubble growth during reionization with computational cosmologist Marcelo Alvarez of the Kavli Institute for Particle Astrophysics and Cosmology. At the SULI farewell barbeque two weeks ago, SLAC Director Persis Drell spoke to the students and their mentors about the many researchers she has met who got their start in the SULI program. Drell wrote in her weekly SLAC Today column, "As our visitors return to their home institutions for the fall term, we wish them well and look forward to meeting them again as they pursue their careers, enriched, we hope, by their summer with us." |
