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 421

Mission Week 421 continues the 50-degree sky-survey rocking profile. The week begins with a 10-minute inertial point observation during which the new survey profile is uploaded. There are no special observations scheduled during this week.

Addressing Questions About Scientific Certainty

In April, the NASA Fermi Gamma-ray Burst Monitor (GBM) team announced the discovery of a weak gamma-ray burst that may be associated with the recent LIGO discovery of gravitational waves from a black hole merger, an event known as GW150914. The team notes that Fermi observations associated with future LIGO/Virgo gravitational wave detections are needed to reveal whether this weak burst is a plausible counterpart or a chance coincidence. The NASA Fermi team stands behind this finding, which has successfully passed through the scientific review process and is awaiting publication in a special issue of The Astrophysical Journal.

NASA's Fermi Telescope Helps Link Cosmic Neutrino to Blazar Blast

Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving at Earth in 2012. Now astronomers using data from NASA's Fermi Gamma-ray Space Telescope and other space- and ground-based observatories have shown that a record-breaking neutrino seen around the same time likely was born in the same event.

Two New Online Services

Two new online services have recently been added to the FSSC web site. The Fermi All-sky Variability Analysis (FAVA) employs a photometric technique to identify flaring sources in the Fermi LAT data and also offers a capability to for end users to compute light curves for any point on the sky for user specified time intervals. A second facility, maintained by the NASA Marshall Space Flight Center, provides a tabulation of candidate Untriggered GBM Short GRB Candidates. With the graphical and textual information provided, users can easily obtain the digital data from the FSSC data archive and perform their own detailed analyses.
