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 374

Mission Week 374 starts with a 10 minute "freeze" observation during which the updated survey profile for this week is loaded. That profile, using the regular 50 degree rock angle, then continues for the remainder of the week. This week is the start of Cycle 8 and observation IDs corresponding to this are now being used. No special observations are scheduled for this week.

Fermi-LAT Data Issue

There was a small glitch in Fermi-LAT data processing that has caused problems with a small amount of LAT data. This involved a problem with the detector calibration constants used in the LAT data processing pipeline that affected all the data corresponding to UTC 2015-07-27 19:04:46.642804 to 2015-07-30 11:03:18.085494.

NASA's Fermi Sees Record Flare from a Black Hole in a Distant Galaxy

Five billion years ago, a great disturbance rocked a region near the monster black hole at the center of galaxy 3C 279. On June 14, the pulse of high-energy light produced by this event finally arrived at Earth, setting off detectors aboard NASA's Fermi Gamma-ray Space Telescope and other satellites. Astronomers around the world turned instruments toward the galaxy to observe this brief but record-setting flare in greater detail.

Astronomers Predict Fireworks from Rare Stellar Encounter in 2018

Astronomers are gearing up for high-energy fireworks coming in early 2018, when a stellar remnant the size of a city meets one of the brightest stars in our galaxy. The cosmic light show will occur when a pulsar discovered by NASA's Fermi Gamma-ray Space Telescope swings by its companion star. Scientists plan a global campaign to watch the event from radio wavelengths to the highest-energy gamma rays detectable.
