Fermi Gamma-ray Space Telescope

The Fermi Science Support Center (FSSC) runs the guest investigator program, creates and maintains the mission time line, provides analysis tools for the scientific community, and archives and serves the Fermi data. This web site is the portal to Fermi for all guest investigators.

This view shows the entire sky at energies greater than 1 GeV based on five years of data from the LAT instrument on NASA's Fermi Gamma-ray Space Telescope. Brighter colors indicate brighter gamma-ray sources.

Look into the "Resources" section for finding schedules, publications, useful links etc. The "Proposals" section is where you will be able to find the relevant information and tools to prepare and submit proposals for guest investigator projects. At "Data" you will be able to access the Fermi databases and find the software to analyse them. Address all questions and requests to the helpdesk in "Help".

Fermi Observations for MW 766

Mission Week 766 begins with a continuation of the symmetric +/-50 deg. profile from the previous week. Then, on DOY 33 (2023-2-2) at 01:30 UT a 10-minute freeze observation occurs during which a symmetric +/-50 deg. profile is loaded. This profile continues until the end of the mission week. Note that positive rock angles are south, and negative rock angles are north.

NASA's Fermi Detects First Gamma-Ray Eclipses From 'Spider' Star Systems

Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar - the superdense, rapidly rotating remains of a star that exploded in a supernova - that slowly erodes its companion.
