Abstract

Mass accretion rates in dimensionless and physical units, and efficiency factors describing the total radiant luminosity of the disk and the beam power of the outflow are studied here. Four samples of sources including 576 LINERs, 100 classical double (FRII) radio sources, 80 relatively local AGN, and 103 measurements of four stellar mass X-ray binary systems, referred to as Galactic Black Holes (GBH), are included in the study. All of the sources have highly collimated outflows leading to compact radio emission or powerful extended (FRII) radio emission. The properties of each of the full samples are explored, as are those of the four individual GBH, and sub-types of the FRII and local AGN samples. Source types and sub-types that have high, medium, and low values of accretion rates and efficiency factors are identified and studied. A new efficiency factor that describes the relative impact of black hole spin and mass accretion rate on the beam power is defined and studied, and is found to provide a new and interesting diagnostic. Mass accretion rates for 13 sources and efficiency factors for 6 sources are compared with values obtained independently, and indicate that similar values are obtained with independent methods. The mass accretion rates and efficiency factors obtained here substantially increase the number of values available, and improve our understanding of their relationship to source types. The redshift dependence of quantities is presented and the impact on the results is discussed.

超过750 AGN和多个GBH的黑洞质量吸积率和效率因子
本文研究了无量纲和物理单位的质量吸积率,以及描述圆盘总辐射光度和流出光束功率的效率因子。该研究包括四个源样本,包括576个liner, 100个经典双(FRII)射电源,80个相对局部AGN,以及103个被称为银河系黑洞(GBH)的四个恒星质量x射线双星系统的测量结果。所有的源都有高度准直的流出,导致紧凑的射电发射或强大的扩展(FRII)射电发射。研究了每个完整样本的性质,以及四个单独的GBH的性质,以及FRII和局部AGN样本的亚型。识别并研究了具有高、中、低吸积速率和效率因子值的烃源类型和子类型。定义并研究了描述黑洞自旋和质量吸积速率对光束功率的相对影响的一个新的效率因子,发现它提供了一种新的有趣的诊断方法。将13个源的质量吸积率和6个源的效率因子与独立获得的值进行了比较,表明用独立方法获得的值相似。这里获得的质量吸积率和效率因子大大增加了可用值的数量,并提高了我们对它们与源类型之间关系的理解。给出了量的红移依赖关系,并讨论了其对结果的影响。
