论文摘要
研究身份不明的γ射线来源很重要，因为它们可能会隐藏新发现。我们对3FGL目录中的13个未识别的费米LAT来源进行了多波长分析，该目录中没有已知的对应物（未识别的伽马射线源，UNIDS）。选择该样本的来源，这些来源在其不确定性椭圆中具有单个无线电和X射线候选对应物。这项研究的目的是找到可能的Blazar签名，并使用经验对数抛物线模型对所选源的光谱能量分布（SED）进行建模。结果表明，红外（IR）带中所有源的同步发射峰，并且MEV中的高能量发射峰到GEV频段。我们样本中的来源的SED都像Blazar一样。此外，样品的峰位置表明，有6个源（46％）是低同步子峰（LSP）Blazars，其中4个（31％）是高同步器峰（HSP）Blazars，而其中3个（23％）是中间的同步峰（ISP）Blazars。
Studying unidentified γ-ray sources is important as they may hide new discoveries. We conducted a multiwavelength analysis of 13 unidentified Fermi-LAT sources in the 3FGL catalog that have no known counterparts (Unidentified Gamma-ray Sources, UnIDs). The sample was selected for sources that have a single radio and X-ray candidate counterpart in their uncertainty ellipses. The purpose of this study is to find a possible blazar signature and to model the Spectral Energy Distribution (SED) of the selected sources using an empirical log parabolic model. The results show that the synchrotron emission of all sources peaks in the infrared (IR) band and that the high-energy emission peaks in MeV to GeV bands. The SEDs of sources in our sample are all blazar like. In addition, the peak position of the sample reveals that 6 sources (46%) are Low Synchrotron Peaked (LSP) blazars, 4 (31%) of them are High Synchrotron Peaked (HSP) blazars, while 3 of them (23%) are Intermediate Synchrotron Peaked (ISP) blazars.
