NASA's Fermi Traces Source of Cosmic Neutrino to Monster Black Hole

For the first time ever, scientists using NASA's Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at almost the speed of light before being detected on Earth. This is farther than any other neutrino whose origin scientists can identify.

Fermi Resumes Science Operations

Both instruments on Fermi have been returned to operational status and are actively collecting science data. For the LAT, this data will be used to monitor performance as the instrument returns to normal operating temperatures. GBM has returned to full functionality.

Update on Fermi Operations

Fermi was commanded out of sun-point mode earlier today (3/27). It is now oriented at a 50 degree rock angle (towards the northern hemisphere) with respect to the zenith. Operations at a fixed rock angle will continue while spacecraft performance is monitored. We plan to start bringing the instruments back online over the next week or so - GBM first and then the LAT. We will post updates on the status of the observatory as the recovery proceeds.

Fermi Spacecraft Operational Anomaly

At 5:11 UT on March 16, Fermi encountered an issue with the solar array drive that caused the observatory to go into safe hold. In this mode, the instruments are powered off, and thus science data taking has stopped. Initial investigation suggests that one of the solar panels is stuck.

Investigation into the cause of the anomaly is ongoing and will continue for some time. We are exploring options to resume some science operations with a fixed solar panel which would run while the anomaly investigations are ongoing. The team is planning to start a return to science ops next week, to run in parallel with the ongoing engineering investigation.

Fermi Friday: Behind the Scenes

To understand black holes at the centers of distant galaxies, scientists combine Fermi data with information from other wavebands. By viewing these objects in the radio, we can see how their jets change over time.

2018 Rossi Prize

Dr. Colleen Wilson-Hodge and the Fermi Gamma-Ray Burst Monitor team were awarded the prestigious 2018 Rossi Prize by the High-Energy Astrophysics Division of the American Astronomical Society for their discovery of gamma rays coincident with a neutron-star merger gravitational wave event, confirming that short gamma-ray bursts are produced by binary neutron-star mergers. The Rossi prize is awarded annually "for a significant contribution to High Energy Astrophysics, with particular emphasis on recent, original work.

Preliminary LAT 8-year Point Source List

As a prelude to the forthcoming Fermi LAT 4FGL catalog, a preliminary list of sources (FL8Y) based on 8-years of integration and employing the up-to-date (PASS-8) calibrations and event selections has been made available to the community through the FSSC by the LAT instrument team. This release is primarily intended to support the preparation Cycle-11 Fermi Guest Investigator proposals. We stress its preliminary nature and strongly encourage users to carefully read the accompanying documentation.
