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 713

Mission week 713 starts with a continuation of the +/-50 deg. rocking profile from the previous week. On day of year 028 (2022-01-28) at 03:50 UT there is a 10-minute freeze observation during which an updated +/-50 deg. profile is loaded. That profile continues until the end of the mission week. Note that positive rock angles are south, and negative angles are north.

LAT Light Curve Repository

The Fermi Large Area Telescope Collaboration has released a repository of flux light curves for more than 1500 variable sources from the LAT catalog calculated on 3-day, 1-week, and 1-month time intervals. The light curves will be frequently updated as new data arrives. The web interface to the repository provides a visualization capability with catalog overlays as well as a search feature. You can find a additional details here.
