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 672

Mission week 672 starts with a continuation of the symmetric rocking profile from the previous week. On day of year 105 (2021-04-15 ) at 01:23 there is a 10 minute freeze observation during which an updated symmetric profile is loaded. This profile continues until DOY 106 (2021-04-16) at 20:11 when there is a 10 minute freeze observation during which an asymmetric +50/-60 deg. profile is loaded. This profile continues until DOY 109 (2021-04-19) at 14:50 when there is another 10 minute freez observation during which a modified sine profile is loaded. This profile continues until the end of the week. Note that positive rock angles are south, and negative angles are north.

Fermi Cycle 14 Proposal Deadline Extended

Owing to the severe weather situation and power outages in Texas and other areas NASA has decided to postpone the Fermi Cycle-14 proposal deadline until March 1, 2021, 16:30 EST. If you have already submitted a proposal you need not resubmit unless you wish to make changes which you may do up to the new deadline. Submission procedures are otherwise unchanged; refer to our website for details.

Fermi Cycle 14 Proposer Workshop

The deadline for Fermi Cycle 14 Guest Investigator proposals is coming soon: Feb 19 at 16:30 EST. To help you prepare your proposals, the project and science support center will host a virtual workshop to provide information about updates to the program (for example, preparing proposals for dual anonymous review) and to provide support for new proposers. Please register using this form by Feb 1 so that we can send you the details to join the virtual meeting.

NASA Missions Unmask Magnetar Eruptions in Nearby Galaxies

On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA and European spacecraft. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.
