来自黑洞内吸积盘的相对论X射线

Relativistic X-ray Lines from the Inner Accretion Disks Around Black Holes

J. M. Miller

摘要:

综述了黑洞周围内吸积盘的相对论性X射线发射谱线。最近钱德拉X射线天文台、X射线多镜任务-牛顿和朱雀的观测显示,这些线是强引力效应的良好探测器。一些重要的观测和理论的发展是突出的,包括黑洞的自旋和影响,如引力光弯曲的证据,在恒星质量的黑洞的相对论性线的检测,和轨道时间尺度线通量变化的证据。此外,相对论盘线对吸收,散射和连续效应的鲁棒性进行了讨论。最后,展望了改进黑洞自旋测量方法和在黑洞-星系共同演化背景下理解超大质量黑洞自旋历史的前景。最好的数据和最严格的结果强烈表明,相对论性X射线盘线可以推动未来对广义相对论和盘物理的探索。

英文摘要:

Relativistic X-ray emission lines from the inner accretion disk around black holes are reviewed. Recent observations with the Chandra X-ray Observatory, X-ray Multi-Mirror Mission-Newton, and Suzaku are revealing these lines to be good probes of strong gravitational effects. A number of important observational and theoretical developments are highlighted, including evidence of black hole spin and effects such as gravitational light bending, the detection of relativistic lines in stellar-mass black holes, and evidence of orbital-timescale line flux variability. In addition, the robustness of the relativistic disk lines against absorption, scattering, and continuum effects is discussed. Finally, prospects for improved measures of black hole spin and understanding the spin history of supermassive black holes in the context of black hole-galaxy co-evolution are presented. The best data and most rigorous results strongly suggest that relativistic X-ray disk lines can drive future explorations of General Relativity and disk physics.
