论文摘要
语境。伽马射线发射源明智的J141046.00+740511.2通过与Swift/XRT数据交叉匹配，已与费米LAT检测相关联。它显示了BL LAC源的所有规范观察性特征，包括幂律，无特征光谱。但是，它直到最近才在无线电频率下检测到，其无线电通量显着较低。目标。鉴于无线电检测是将低能量对应物与费米 - 拉特源相关联的基础，因此我们旨在通过基于同时数据进行多波长分析来明确地对此源进行分类。方法。通过在Jansky上使用多频观测，非常大的阵列，巨大的Metrewave射电望远镜，Gran Telescopio Canarias，Gemini，William Herschel望远镜和Liverpool天文台，以及Fermi-Lat和Swift Data，我们进行了两种分析。一方面，我们研究了几个已知参数，这些参数解释了无线电响度或弱点的表征及其对Blazars（通常）（尤其是）（尤其是）的应用。另一方面，我们构建并分析了该来源的观察到的光谱分布（SED），以试图解释其特殊的特征。结果。多波长分析表明，明智的J141046.00+740511.2是高频峰（HBL）类型的大黄花，它发出高度极化的光，可能位于低红移。此外，最适合其SED的单区模型参数是极端HBL（EHBL）的参数；从理论上讲，这种大型类型在无线电发射中缺乏广泛的预测，而无线电发射是典型的典型伽马射线布拉兹。结论。我们确认明智的J141046.00+740511.2确实是HBL类型的高度极化的BL LAC。将进行进一步的研究，以解释该来源检测到的非典型低无线电通量。
Context. The gamma-ray emitting source WISE J141046.00+740511.2 has been associated with a Fermi-LAT detection by crossmatching with Swift/XRT data. It has shown all the canonical observational characteristics of a BL Lac source, including a power-law, featureless optical spectrum. However, it was only recently detected at radio frequencies and its radio flux is significantly low. Aims. Given that a radio detection is fundamental to associate lower-energy counterparts to Fermi-LAT sources, we aim to unambiguously classify this source by performing a multiwavelength analysis based on contemporaneous data. Methods. By using multifrequency observations at the Jansky Very Large Array, Giant Metrewave Radio Telescope, Gran Telescopio Canarias, Gemini, William Herschel Telescope and Liverpool observatories, together with Fermi-LAT and Swift data, we carried out two kinds of analyses. On one hand, we studied several known parameters that account for the radio loudness or weakness characterization and their application to blazars (in general) and to our source (in particular). And, on the other hand, we built and analyzed the observed spectral energy distribution (SED) of this source to try to explain its peculiar characteristics. Results. The multiwavelength analysis indicates that WISE J141046.00+740511.2 is a blazar of the high-frequency peaked (HBL) type that emits highly polarized light and that is likely located at a low redshift. In addition, the one-zone model parameters that best fit its SED are those of an extreme HBL (EHBL); this blazar type has been extensively predicted in theory to be lacking in the radio emission that is otherwise typical of canonical gamma-ray blazars. Conclusions. We confirm that WISE J141046.00+740511.2 is indeed a highly polarized BL Lac of the HBL type. Further studies will be conducted to explain the atypical low radio flux detected for this source.
