Fermi Large Area Telescope Bright Gamma-ray Source List

TL;DR

This paper presents the initial catalog of the brightest gamma-ray sources detected by the Fermi LAT, providing the most detailed and well-localized gamma-ray sky map to date for energies above 100 MeV.

Contribution

It introduces the first comprehensive list of the most significant gamma-ray sources detected by Fermi LAT, with improved resolution and localization compared to previous missions.

Findings

Identification of 205 significant gamma-ray sources

Enhanced resolution and localization of gamma-ray sources

First detailed catalog of bright gamma-ray sources from Fermi LAT

Abstract

Following its launch in June 2008, the Fermi Gamma-ray Space Telescope (Fermi) began a sky survey in August. The Large Area Telescope (LAT) on Fermi in 3 months produced a deeper and better-resolved map of the gamma-ray sky than any previous space mission. We present here initial results for energies above 100 MeV for the 205 most significant (statistical significance greater than ~10-sigma) gamma-ray sources in these data. These are the best-characterized and best-localized point-like (i.e., spatially unresolved) gamma-ray sources in the early-mission data.
