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 Observing Mode Change

On Thursday, April 24th, Fermi returned to a survey mode that provides more uniform coverage over the entire sky. This observing mode, the same one that has been in place for the majority of the mission, allows the observatory to improve exposure during the period surrounding the periastron passage of the pulsar B1259-63. For information about Fermi observations of the previous periastron event, click here.

Gamma-Ray Burst Localizations

The Fermi Science Support Center and the GBM team are pleased to announce the availability of new data products related to the localization of Gamma-Ray Bursts (GRBs). In addition to the positions on the sky and their 68% confidence level statistical errors, communicated via notices from the GRB Coordinates Network (GCN), probability maps incorporating the total error on the final, best localization will be delivered. These products a may be available as soon as 30 minutes following the GRB trigger. A description of the data products is given in the README file in these quicklook directories, e.g., README.

Fermi Data Tantalize With New Clues To Dark Matter

A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the Harvard-Smithsonian Center for Astrophysics (CfA), the Massachusetts Institute of Technology (MIT) and the University of Chicago have developed new maps showing that the galactic center produces more high-energy gamma rays than can be explained by known sources and that this excess emission is consistent with some forms of dark matter.
