论文摘要
我们继续在Karasev等人开始研究。 （2018年），并介绍了我们对整体天空调查的四个硬X射线源的光学标识的结果。首先使用Swift天文台的X射线望远镜（XRT）改善了这些物体在天空中的位置后，我们使用光学和红外天空调查数据确定了它们的对应物。然后，我们获得了与RTT-150俄罗斯 - 土耳其望远镜和AZT-33IK望远镜的假定对应物的光谱。这允许确定正在研究的物体的性质。源IGR J11079+7106和IGR J12171+7047的来源本质上已经是外层状的，并且分别为Seyfert 1和2星系，第二个物体的特征是吸收柱密度较大。源IGR J18165-3912很可能是具有很高光度的中间极性。第四个来源IGR J20596+4303是两个对象的机会叠加 - seyfert 2 Galaxy和一个灾难性变量。
We continue the study begun in Karasev et al. (2018) and present the results of our optical identifications of four hard X-ray sources from the INTEGRAL sky surveys. Having first improved the positions of these objects in the sky with the X-ray telescope (XRT) of the Swift observatory, we have identified their counterparts using optical and infrared sky survey data. Then, we have obtained optical spectra for the supposed counterparts with the RTT-150 Russian-Turkish telescope and the AZT-33IK telescope. This has allowed the nature of the objects under study to be established. The sources IGR J11079+7106 and IGR J12171+7047 have turned out to be extragalactic in nature and be Seyfert 1 and 2 galaxies, respectively, with the second object being characterized by a large absorption column density. The source IGR J18165-3912 is most likely an intermediate polar with a very high luminosity. The fourth source, IGR J20596+4303, is a chance superposition of two objects - a Seyfert 2 galaxy and a cataclysmic variable.
