摘要:

我们提出了第一个目录的高置信度伽马射线源检测的AGILE卫星在2007年7月9日至2008年6月30日进行的观测。通过合并整个时间段内的所有可用数据来检测编目源。AGILE于2007年4月发射,是意大利航天局的一项飞行任务,专门用于30 MeV - 50 GeV能量范围内的伽马射线观测,具有18-60 keV波段的同步X射线成像能力。该目录基于能量大于100 MeV的伽马射线成像探测器(GRID)数据。对于第一个AGILE星表,我们采用了保守的分析方法,使用了高质量的事件过滤器,以选择仪器视场中心区域(半径为40度)内的伽马射线事件。这是一个重要性有限(4 sigma)的星表,由于AGILE第一年的天空覆盖不均匀,它不是一个完整的通量有限样本。该星表包括47个源,其中21个与已确认或候选的恒星有关,13个与Blazar有关(7个FSRQ,4个BL Lac,2个未知类型),2个与HMXRB有关,2个与SNR有关,1个与碰撞风双星系统有关,8个与未确认的源有关。

英文摘要:

We present the first catalog of high-confidence gamma-ray sources detected by the AGILE satellite during observations performed from July 9, 2007 to June 30, 2008. Catalogued sources are detected by merging all the available data over the entire time period. AGILE, launched in April 2007, is an ASI mission devoted to gamma-ray observations in the 30 MeV - 50 GeV energy range, with simultaneous X-ray imaging capability in the 18-60 keV band. This catalog is based on Gamma-Ray Imaging Detector (GRID) data for energies greater than 100 MeV. For the first AGILE catalog we adopted a conservative analysis, with a high-quality event filter optimized to select gamma-ray events within the central zone of the instrument Field of View (radius of 40 degrees). This is a significance-limited (4 sigma) catalog, and it is not a complete flux-limited sample due to the non-uniform first year AGILE sky coverage. The catalog includes 47 sources, 21 of which are associated with confirmed or candidate pulsars, 13 with Blazars (7 FSRQ, 4 BL Lacs, 2 unknown type), 2 with HMXRBs, 2 with SNRs, 1 with a colliding-wind binary system, 8 with unidentified sources.
