Fermi Gamma-ray Space Telescope

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 581

Mission week 581 starts with a continuation of the modified sine profile from the previous week. At 01:14 UT on day of year 199 there is a 10 minute freeze observation during which an updated modified sine profile is loaded. Then, on DOY 202 at 13:20 UT there is another 10 minute freeze observation during which a second update to the profile is loaded. This profile continues until the end of the mission week. Note that positive rock angles are south, and negative angles are north.

NASA's Fermi Mission Reveals its Highest-energy Gamma-ray Bursts

For 10 years, NASA's Fermi Gamma-ray Space Telescope has scanned the sky for gamma-ray bursts (GRBs), the universe's most luminous explosions. A new catalog of the highest-energy blasts provides scientists with fresh insights into how they work.

NASA's Fermi Satellite Clocks 'Cannonball' Pulsar Speeding Through Space

Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour - so fast it could travel the distance between Earth and the Moon in just 6 minutes. The discovery was made using NASA’s Fermi Gamma-ray Space Telescope and the National Science Foundation's Karl G. Jansky Very Large Array (VLA).
