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 445

Mission Week 445 starts with a 10 minute freeze observation during which an updated survey profile using the regular 50 degree rock angle. That profile continues until DOY 347 00:00 UT when another 10 minute freeze observation is begun and a survey profile using a 55 degree rock angle is loaded. The 55 degree profile is used for the remainder of the week because the predicted beta angle exceeds the 45 degree threshold during that time.

NASA's Fermi Finds Record-breaking Binary in Galaxy Next Door

Using data from NASA's Fermi Gamma-ray Space Telescope and other facilities, an international team of scientists has found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a cyclic flood of gamma rays, the highest-energy form of light.

New Version of the Fermi Science Tools

The FSSC is pleased to announce the availability of a version of the Fermi Science Tools that can be built from source on OS X 15.6 (el Capitan). This release is *only* for users with problems using the binary version of the tools on el Capitan. Users should be aware that this version of the tools does not support the ROOT or gtburst software.

NASA's Fermi Mission Expands its Search for Dark Matter

Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, the results are helping scientists rule out some of the many theoretical possibilities. Three studies published earlier this year, using six or more years of data from NASA's Fermi Gamma-ray Space Telescope, have broadened the mission's dark matter hunt using some novel approaches.
