论文摘要
$ \ textit {fermi gamma-ray空间望远镜} $中大约有三分之一的现有$γ$ ray来源被认为是无关的，在其他频率/波长中没有已知的对应物。这些来源一直是观测员任务寿命期间进行严格审查和观察性努力的主题，在这里我们提出了一种利用现有无线电目录检查这些来源的方法，而无需特定的专用观察结果，这可能是昂贵且复杂的。通过包含许多敏感的低频目录，我们专门针对陡峭的频谱来源，例如脉冲星。这项工作发现591 $ \ textit {fermi} $无相关的田野中包含的陡峭光谱无线电源，其中至少有21个以具有Pulsar样$γ$ -Ray属性而闻名。我们还根据各种无线电和$γ$ ray的选择来确定许多其他感兴趣的领域。
Approximately one-third of existing $γ$-ray sources identified by the $\textit{Fermi Gamma-Ray Space Telescope}$ are considered to be unassociated, with no known counterpart at other frequencies/wavelengths. These sources have been the subject of intense scrutiny and observational effort during the observatory's mission lifetime, and here we present a method of leveraging existing radio catalogs to examine these sources without the need for specific dedicated observations, which can be costly and complex. Via the inclusion of many sensitive low-frequency catalogs we specifically target steep spectrum sources such as pulsars. This work has found steep-spectrum radio sources contained inside 591 $\textit{Fermi}$ unassociated fields, with at least 21 of them being notable for having pulsar-like $γ$-ray properties as well. We also identify a number of other fields of interest based on various radio and $γ$-ray selections.
