黑洞天体活动的基本面研究

Research on the Fundamental Plane of Black Hole Activity

活动星系核(中心黑洞质量MBH^10^6-10^10M⊙)和黑洞X射线双星(MBH^10M⊙)普遍被认为具有相似的中心引擎:黑洞、吸积盘和喷流.类似的中心引擎、质量相却差如此之大(6{9个数量级)的两类黑洞系统是否具有相似的物理仍不清楚.本文围绕不同尺度黑洞天体的物理性质和观测特性展开,主要研究了不同尺度黑洞天体活动的基本面关系以及黑洞X射线双星的能谱演化.

It is generally believed that active galactic nuclei(AGNs)and black hole X-ray binaries(BHXRBs)have a similar central engine:black hole(BH),accretion disc,and jet.Whether the two kinds of sources with 6-10 orders magnitude differences in BH masses have a similar physical properties is still unknown.In this paper,we explore the physical properties in these BH sources,and especially investigate the possible universal correlations for these different-scale BH sources.
