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.

Fermi Data Tantalize With New Clues To Dark Matter

A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the Harvard-Smithsonian Center for Astrophysics (CfA), the Massachusetts Institute of Technology (MIT) and the University of Chicago have developed new maps showing that the galactic center produces more high-energy gamma rays than can be explained by known sources and that this excess emission is consistent with some forms of dark matter.

Second GBM Catalog of Gamma-Ray Bursts Available in HEASARC Browse

The Fermi Science Support Center and the GBM Team are pleased to announce the availability of the second GBM catalog of Gamma-Ray Bursts (GRBs) in the HEASARC browse interface. The catalog will soon appear in the Astrophysical Journal (Supplement Series). This catalog is in two parts: a general description (A. von Kienlin et al., http://arxiv.org/abs/1401.5080) and a spectral analysis (D. Gruber et al., http://arxiv.org/abs/1401.5069). The general catalog includes 953 GRBs that triggered GBM between 2008-07-12 and 2012-07-11. The spectral catalog reports spectral analyses of 943 GRBs, including revised analyses of the GRBs in the first catalog, from 2008-07-12 to 2010-07-11. Data from these catalogs are now available at the HEASARC in searchable tables via the Browse interface.

With A Deadly Embrace, 'Spidery' Pulsars Consume Their Mates

Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.
