论文摘要
我们与HyperLeDA数据库交叉匹配了4xMM-DR10目录，并获得了包含X射线源的新样本。除了重复观测和虚假匹配外，我们总共提供了7759个带有X射线源的星系。在当前的工作中，我们介绍了样本的一般特性：即赤道坐标的分布，径向速度分布，形态类型和X射线通量。该样品包括具有X射线发射的5241个星系的形态分类，其中几乎一半为42 \％，是椭圆形的（E，E-S0）。样品中的大多数星系具有核X射线发射（6313或81 \％），其余的1443（19 \％）呈现X射线发射，X射线发射来自宿主星系。该样品可用于对具有X射线发射的星系的多波长性质的未来深入研究。
We cross-matched the 4XMM-DR10 catalog with the HyperLEDA database and obtained the new sample of galaxies that contain X-ray sources. Excluding duplicate observations and false matches, we present a total of 7759 galaxies with X-ray sources. In the current work, we present general properties of the sample: namely the distribution in equatorial coordinates, radial velocity distribution, morphological type, and X-ray fluxes. The sample includes morphological classification for 5241 galaxies with X-ray emission, almost half of which, 42\%, are elliptical (E, E-S0). Most galaxies in the sample have nuclear X-ray emission (6313 or 81\%), and the remaining 1443 (19\%) present X-ray emission from the host galaxy. This sample can be used for future deep studies of multi wavelengths properties of the galaxies with X-ray emission.
