论文摘要

提出了由费米大区域望远镜检测到的活性银河核（AGN）的第四个目录的增量版本。此版本（4LAC-DR3）源自4FGL目录的第三个数据发布，基于E> 50 MeV伽马射线数据的12年，其中光谱参数，光谱能量分布（SEDS），年度光曲线和关联已更新所有源。新报道的AGN包括587名Blazar候选人和四个射电星系。我们描述了新样本的属性和概述变化，影响了先前发布的样本。我们还在此版本中引入了两个新参数，即SED高能量分量和相应的通量的峰值能量。这些参数允许评估康普顿的优势，而无需依赖X射线数据，反compton与同步加速器峰的光度的比率。

An incremental version of the fourth catalog of active galactic nuclei (AGNs) detected by the Fermi-Large Area Telescope is presented. This version (4LAC-DR3) derives from the third data release of the 4FGL catalog based on 12 years of E>50 MeV gamma-ray data, where the spectral parameters, spectral energy distributions (SEDs), yearly light curves, and associations have been updated for all sources. The new reported AGNs include 587 blazar candidates and four radio galaxies. We describe the properties of the new sample and outline changes affecting the previously published one. We also introduce two new parameters in this release, namely the peak energy of the SED high-energy component and the corresponding flux. These parameters allow an assessment of the Compton dominance, the ratio of the Inverse-Compton to the synchrotron peak luminosities, without relying on X-ray data.
