我们提出的第一个目录的活动星系核（AGN）检测的大面积望远镜（LAT），对应于11个月的数据收集的科学操作模式。第一个LATAGN目录（1LAC）包括671个位于银河系高纬度的γ射线源（|B|>10°），其检验统计量大于25，并与活动星系核统计相关。一些LAT源与多个活动星系核相关联，因此，该目录包括709个活动星系核，其中包括300个BL Lacertae天体，296个平谱射电类星体，41个其他类型的活动星系核和72个未知类型的活动星系核。我们还根据档案无线电，光学和X射线数据允许的光谱能量分布对耀变体进行分类。除了正式的1LAC样本，我们提供活动星系核协会为51个低纬度LAT源和活动星系核的“附属”（未量化的对应候选人）为104个高纬度LAT源没有活动星系核协会。简要讨论了1LAC与现有的γ射线活动星系核目录（LBAS，EGRET，AGILE，Swift，INTEGRAL，TeVCat）的重叠问题。各种属性，如γ射线通量和光子幂律谱指数，红移，γ射线光度，可变性和档案射电光度和它们的相关性，并讨论了不同的耀变体类。我们比较了1LAC的结果与预测的γ射线活动星系核的人口，我们评论的电源的样本，以解决问题的耀变体序列。
We present the first catalog of active galactic nuclei (AGNs) detected by the Large Area Telescope (LAT), corresponding to 11 months of data collected in scientific operation mode. The First LAT AGN Catalog (1LAC) includes 671 γ-ray sources located at high Galactic latitudes (|b|>10°) that are detected with a test statistic greater than 25 and associated statistically with AGNs. Some LAT sources are associated with multiple AGNs, and consequently, the catalog includes 709 AGNs, comprising 300 BL Lacertae objects, 296 flat-spectrum radio quasars, 41 AGNs of other types, and 72 AGNs of unknown type. We also classify the blazars based on their spectral energy distributions as archival radio, optical, and X-ray data permit. In addition to the formal 1LAC sample, we provide AGN associations for 51 low-latitude LAT sources and AGN “affiliations” (unquantified counterpart candidates) for 104 high-latitude LAT sources without AGN associations. The overlap of the 1LAC with existing γ-ray AGN catalogs (LBAS, EGRET, AGILE, Swift, INTEGRAL, TeVCat) is briefly discussed. Various properties—such as γ-ray fluxes and photon power-law spectral indices, redshifts, γ-ray luminosities, variability, and archival radio luminosities—and their correlations are presented and discussed for the different blazar classes. We compare the 1LAC results with predictions regarding the γ-ray AGN populations, and we comment on the power of the sample to address the question of the blazar sequence.
