Fermi Science Support Center

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 352

This week continues the 50-degree sky-survey rocking profile. The new survey profile is uploaded during a short (10 minute) inertial point observation at the beginning of the mission week. There are no special observations scheduled during this week.

Third Catalog of Fermi-LAT Sources Released

The 3FGL catalog is based on the first four years of LAT science data. It contains 3033 sources of gamma-rays from 100 MeV to 300 GeV. The catalog is provided as a FITS table and as PDF files, and is accompanied by important caveats as well as a draft of the paper describing the details of the catalog preparation. The 3FGL catalog represents a major milestone and is a great accomplishment by the international Fermi-LAT team.
