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 321

This week continues the interleaved inertial point + sky-survey profiles. For the first 2.75 days the inertial point target is the TOO target S3 0218+357. The remainder of the week uses targets designed to increase exposure on the Galactic center. The week starts with a continuation of the sky-survey from the previous week. The updated profile is loaded at 207-18:39, during the first galactic-center-focused inertial point observation of the week.

NASA's Fermi Finds A 'Transformer' Pulsar

In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA's Fermi Gamma-ray Space Telescope.

Temporary Disruption of GBM Data Delivery

A planned outage at the National Space Science and Technology Center (NSSTC) in Huntsville over the weekend of 12-13 July will result in delayed delivery of some GBM data products. A backup pipeline will be in place by noon EDT Friday 11. GRB alerts and localization notices should be broadcast through the GRB Coordinates Network without extra latency but refined localization products and GRB response file delivery may be delayed. Trigger CTIME, CSPEC, and TTE data products will be produced by the backup pipeline but daily CTIME, CSPEC, and position history files will not. Operations at NSSTC should be nominal on July 14 at which time the missing data products will be delivered to the FSSC.
