Fermi Summer School will be May 26 to June 5, 2026.
The Fermi Large Area Telescope (LAT) has released an early version of the source list (FL16Y) developed for the upcoming 5FGL catalog of LAT sources. The FL16Y list is based on 16 years of survey data covering gamma-ray energies from 50 MeV to 1 TeV. The list, along with supporting documentation and data products, is available on this web page. Compared to the original 4FGL catalog, this new list uses twice as much data. As a result, the precision of source locations has improved by 24% on average.
Registration is now open for the Fermi Summer School 2026. The application deadline is February 6, 2026. However, we have a limited number of positions at the school and early applications will be favored.
The Fermi Science Support Center (FSSC) is hosting a virtual proposal workshop on 14 January 2026 from 2:00-3:30PM EST. Full details, including a link to the registration form, can be found on the Workshop Page. The workshop will include details of the updated Target of Opportunity (TOO) program. Please register by 10AM EST on Jan 14 so that we can send you the details to join the virtual meeting.
