从多波长到质量标度:微类星体和AGN中的吸积和抛射

From Multiwavelength to Mass Scaling: Accretion and Ejection in Microquasars and AGN

S. Markoff

摘要:

尽管经过了几十年的观测,人们仍然缺乏对黑洞和其他致密物体周围流入、吸积等离子体如何产生外流风和喷流的坚实理论理解。在X射线双星和活动星系核中都观察到类似的过程和形态,这一事实导致人们提出,潜在的物理学可以与黑洞质量成比例,这可以为这个问题提供一个新的处理方法。在过去的十年中,同时宽带运动的快速变化的X射线双星,特别是在他们的微类星体的状态已经推动了发展,并在某些情况下改变,我们的想法的流入/流出连接吸积黑洞。特别是无线电,红外和X射线波段之间的相关性的发现揭示了不同发射区域之间的显着连接,并主张采用更全面的方法来解决吸积问题。本文回顾了最近的主要观测和理论进展,特别是侧重于在黑洞的吸积过程的两个“方面”之间的关系,强调如何新的工具可以得到跨质量尺度的比较。

英文摘要:

A solid theoretical understanding of how inflowing, accreting plasma around black holes and other compact objects gives rise to outflowing winds and jets is still lacking, despite decades of observations. The fact that similar processes and morphologies are observed in both X-ray binaries as well as active galactic nuclei has led to suggestions that the underlying physics could scale with black hole mass, which could provide a new handle on the problem. In the last decade, simultaneous broadband campaigns of the fast-varying X-ray binaries particularly in their microquasar state have driven the development of, and in some cases altered, our ideas about the inflow/outflow connection in accreting black holes. Specifically the discovery of correlations between the radio, infrared and X-ray bands has revealed a remarkable connectivity between the various emission regions, and argued for a more holistic approach to tackling questions about accretion. This article reviews the recent major observational and theoretical advances that focus specifically on the relation between the two "sides" of the accretion process in black holes, with an emphasis on how new tools can be derived for comparisons across the mass scale.
