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 347

The week begins with a continuation segment of the previous week's 55-degree sky-survey rocking profile for high beta angles. An inertial point observation is scheduled at 2015-022-09:25 followed by commands to return to 50-degree survey. That profile is used for the remainder of the 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.

Short- and Long-Term Changes to Fermi Observations

For the last year Fermi has been performing a modified observing strategy where inertially pointed observations, to increase exposure around the Galactic center, have been interleaved with sky survey observations. Starting on 2014 December 4, Fermi will return to routinely performing only sky survey observations, with alternate orbits having Fermi rocked north and south of the zenith. Short term changes to this mode may still occur in response to targets of opportunity.

NASA's Fermi Satellite Finds Hints of Starquakes in Magnetar 'Storm'

NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing this data have discovered underlying signals related to seismic waves rippling throughout the magnetar.
