Black-hole masses of type-1 AGNs

We derive masses of the central supermassive black hole (SMBH) and accretion rates for 154 type 1 AGN belonging to a well-defined X-ray-selected sample, the XMM-Newton...我们针对一组定义严谨的XMM-牛顿X射线选源样本中的154个1型活动星系核（AGN, Active Galactic Nucleus），推算了其中心超大质量黑洞（supermassive black hole, SMBH）的质量以及吸积率。
