NASA Missions Monitor a Waking Black Hole

NASA's Swift satellite detected a rising tide of high-energy X-rays from the constellation Cygnus on June 15, just before 2:32 p.m. EDT. About 10 minutes later, the Japanese experiment on the International Space Station called the Monitor of All-sky X-ray Image (MAXI) also picked up the flare.

Pass 8 Data Available for the LAT

The FSSC is pleased to announce the availability of Pass 8 data for the LAT. The Pass 8 data have been reprocessed from the raw data using the latest calibrations and updates. The improvements include a better PSF, improved energy measurement, and increased acceptance across the whole energy band. This data release includes a new method for sub-selecting photons from the event data. In order to analyze Pass 8 data you must upgrade to the new v10r0p5 version of the Fermi science tools.

Aperture Photometry Light Curves for LAT 3FGL Catalog Sources

Aperture photometry light curves of all 3FGL sources with 30 day time resolution, together with power spectra of these, are now available. These will normally be updated weekly. In addition, results of an automatic search for flaring 3FGL sources are also provided with weekly updates. Light curves and power spectra are here. Flaring sources are here.

Third Catalog of Fermi-LAT Sources Released

The 3FGL catalog is based on the first four years of LAT science data. It contains 3033 sources of gamma-rays from 100 MeV to 300 GeV. The catalog is provided as a FITS table and as PDF files, and is accompanied by important caveats as well as a draft of the paper describing the details of the catalog preparation. The 3FGL catalog represents a major milestone and is a great accomplishment by the international Fermi-LAT team.
