摘要
我们给出第四版费米-LAT 伽马射线源表的增量版本（4FGL-DR3，即 Data Release 3）。基于 50 MeV 至 1 TeV 能量范围内前十二年的科学数据，它包含 6658 个源。该分析改进了基于八年数据用于 4FGL 星表的分析：更多源被拟合为弯曲谱，我们为脉冲星引入更稳健的谱参数化，并将能谱点扩展到 1 TeV。所有源的谱参数、谱能量分布和成协关系均被更新。光变曲线以 1 年间隔（而非 2 个月间隔）为所有源重建。在 5064 个原始 4FGL 源中，16 个被删除，112 个在 12 年上正式低于探测阈值（但保留在列表中），而 74 个获得新成协，10 个成协得到改进，7 个成协被撤回。脉冲星被明确划分为年轻脉冲星与毫秒脉冲星。我们报道了在 LAT 源中新探测到的脉冲星和双星，以及超过 100 个新分类的耀变体。我们新增三个扩展源和 1607 个新点源，后者大多刚高于探测阈值，其中八个被视为已证认，699 个在其他波段有合理对应体。我们讨论了全局天空模型的度尺度残差以及靠近银道面的软未成协点源团，它们可能与星际发射模型的局限性和缺失的扩展源有关。
