Fermi Cycle 17 Proposer Workshop

The deadline for Fermi Cycle-17 Guest Investigator proposals is fast approaching: Feb 15, 2024, 16:30 EST. To help you in preparing your proposals, the Fermi Science Support Center will host a virtual workshop on Jan. 24 2024, at 14:00 EST. We will provide information on proposal submission and evaluation processes, as well as the latest mission news. Resources available to proposers and researchers through the FSSC will be described and there will be opportunity for questions. In addition, we will allot time for optional, user-contributions comprised of short (~5min) presentations on your recent or ongoing Fermi-related scientific activities. If you'd like to attend please register using this form by Jan. 23 so that we can send you the details to join the virtual meeting.

NASA's Fermi Mission Creates 14-Year Time-Lapse of the Gamma-Ray Sky

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA's Fermi Gamma-ray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond.

NASA's Fermi Mission Nets 300 Gamma-Ray Pulsars ... and Counting

A new catalog produced by a French-led international team of astronomers shows that NASA's Fermi Gamma-ray Space Telescope has discovered 294 gamma-ray-emitting pulsars, while another 34 suspects await confirmation. This is 27 times the number known before the mission launched in 2008.

Fermi-LAT Daily Aperture Light Curve of T CrB Now Available

T CrB (T Coronae Borealis) is a known recurrent nova with its long-anticipated next explosion expected in early 2024. Because of its proximity (distance ~0.9 kpc), T CrB is expected to be detected brightly as a >100 MeV gamma-ray transient. In consideration of its expected bright outburst in gamma rays, a preliminary daily light curve is publicly available.
