标题： New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes during the First Five SRG All-Sky X-ray Surveys. Part 2

摘要： 我们报告了在米哈伊尔·帕夫林斯基ART-XC望远镜上的SRG天文台的前五个全天空调查的组合图中，在半球上检测到的11个X射线源的结果，这些源在4-12 keV能量带内被检测到。$0^\circ< l <180^\circ$。所有这些源也被SRG/eROSITA望远镜在0.2-8 keV能量带内检测到，其数据使我们能够提高它们的位置精度并研究它们的X射线光谱。其中五个是首次在X射线中被检测到，而其余的先前已被知，但其性质仍不清楚。我们使用1.6米口径的AZT-33IK望远镜在萨彦天文台（俄罗斯科学院太阳地球物理研究所西伯利亚分院）为九个源获取了光学光谱；对于另外两个天体，我们分析了来自SDSS和6dF巡天的档案光谱。这些天体被分类为活动星系核（七个Sy1型，三个Sy1.9型，一个Sy2型），红移为$z$=0.029-0.258。我们对X射线光谱的分析揭示了四个赛弗特2型星系中的两个（Sy1.9-2）存在显著的固有吸收（$N_{\rm H} \sim 10^{22}$cm$^{-2}$）。其中一个（SRGA J000132.9+240237）的光谱无法用吸收的康普顿化连续模型来描述，这可能表明存在强烈的吸收和反射辐射的重要贡献。然而，现有的SRG全天空调查数据不足以对该对象的吸收柱密度获得可靠的限制，这也因为它是射电明亮的而变得有趣。需要更长的X射线观测以精炼这个活动星系核的物理性质。 显示英文摘要

摘要： We present the results of our identification of 11 X-ray sources detected on the half of the sky $0^\circ<l<180^\circ$ in the 4-12 keV energy band on the combined map of the first five all-sky surveys with the Mikhail Pavlinsky ART-XC telescope onboard the SRG observatory. All these sources were also detected by the SRG/eROSITA telescope in the 0.2-8 keV energy band, whose data have allowed us to improve their positions and to investigate their X-ray spectra. Five of them have been detected in X-rays for the first time, while the remaining ones have already been known previously, but their nature has remained unknown. We have taken optical spectra for nine sources with the 1.6-m AZT-33IK telescope at the Sayan Observatory (the Institute of Solar-Terrestrial Physics, the Siberian Branch of the Russian Academy of Sciences); for two more objects we have analyzed the archival spectra from SDSS and the 6dF survey. The objects are classified as Seyfert galaxies (seven Sy1, three Sy1.9, and one Sy2) at redshifts $z$=0.029-0.258. Our analysis of the X-ray spectra has revealed a noticeable intrinsic absorption ($N_{\rm H} \sim 10^{22}$ cm$^{-2}$) in two of the four Seyfert 2 galaxies (Sy1.9-2). The spectrum of one more of them (SRGA J000132.9+240237) cannot be described within the model of an absorbed Comptonization continuum, which may point to a strong absorption and a significant contribution of the reflected radiation. However, the available SRG all-sky survey data are not enough to obtain reliable constraints on the absorption column density in this object, which is also interesting in that it is radio loud. Longer X-ray observations are required to refine the physical properties of this active galactic nucleus.
