Abstract
We present the First Catalogue of high-confidence gamma-ray sources detected by AGILE during observations performed from 9 July 2007 to 30 June 2008. Catalogued sources are detected by merging all the available data over the entire time period. The AGILE satellite, launched in April 2007, is a mission devoted to gamma-ray observations in the 30 MeV - 50 GeV energy range, with simultaneous X-ray imaging in the 18-60 keV band. This Catalog is based on Gamma-Ray Imaging Detector (GRID) data for energies greater than E>100 MeV. For the First AGILE Catalog we adopted a conservative analysis, with a high-quality gamma event filter (with relatively low effective area),optimized to select gamma-ray events within the central zone of the Field of View (radius of 30 degrees). The Catalog includes 40 sources, of which 20 are associated with confirmed and candidate pulsars, 13 with Blazars (7 FSRQ, 4 BL Lacs, 2 unknown type), 2 with possible HMXRBs, 2 with possible SNRs, 3 with unidentified sources.
