【摘要】：正自转作为描述黑洞天体物理性质的两个基本参数之一,其研究正方兴未艾.本文以星系中心超大质量黑洞(SMBH)的自转为研究主题,阐述自转的确定、宇宙学演化及其对黑洞吸积历史的限制.SMBH附近的加速机制使粒子产生甚高能量的辐射,对这些辐射的观测可以给出中心黑洞的信息.基于此,我们提出了利用TeV光变限制黑洞自转参数的方法.基本原理是:TeV光变给出了辐射区域最大尺度的限制,吸积盘辐射场通过对TeV光子的吸收光深给出了辐射区域最小尺度的限制.由于吸积盘辐射场与黑洞自转直接相关,从而结合TeV光变可以限制黑洞自转.对于给定的光度,快
[Abstract]:As one of the two basic parameters to describe the physical properties of black hole, the study of positive rotation is in the ascendant. In this paper, the self-transformation of supermassive black hole (SMBH) in the center of a galaxy is turned into a research topic. The determination of rotation, the cosmological evolution and its limitation on black hole accretion history are discussed. The acceleration mechanism near SMBH causes particles to produce very high energy radiation. Observations of these radiation can give information about the central black hole. Based on this, we propose a method to limit the rotation parameters of black holes by TeV light variation. The basic principle is that the limit of the maximum scale of radiation region is given by the: Tev light variation, and the limit of the minimum scale of the radiation region is given by the radiation field of accretion disk through the absorption depth of TeV photons. Since the accretion disk radiation field is directly related to the rotation of the black hole, the rotation of the black hole can be limited by the combination of TeV light variation. For a given luminosity, fast
