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 342

MW 342 consists of sky survey observations with the standard rock angle of 50 degrees. The week starts with a continuation of the profile from the previous week. Then, at 00:57 on the first day there is a 10 minute pointed "freeze" observation while the updated profile for this week is loaded. That profile then continues for the remainder of the week.

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.

NASA's Fermi Space Telescope Reveals New Source of Gamma Rays

Observations by NASA's Fermi Gamma-ray Space Telescope of several stellar eruptions, called novae, firmly establish these relatively common outbursts almost always produce gamma rays, the most energetic form of light.
