作为极端质量比引力波源动力学实验室的银河系中心

The Galactic Center as a laboratory for extreme mass ratio gravitational wave source dynamics

Tal Alexander

摘要:

大质量银河系黑洞和它周围的恒星是一个独特的实验室,用于研究弛豫过程如何导致恒星和致密残余物与中心大质量黑洞的密切相互作用,特别是那些导致引力波发射的相互作用。我回顾了新的结果,强大的质量分离和损失锥填充的大规模扰动和共振松弛的过程中,描述观测证据表明,这些过程中发挥的作用,在银河系中心,可以在那里进行研究,并讨论了一些极端质量比的影响螺旋事件率及其属性。

英文摘要:

The massive Galactic black hole and the stars around it are a unique laboratory for studying how relaxation processes lead to close interactions of stars and compact remnants with the central massive black hole, in particular those leading to the emission of gravitational waves. I review new results on the processes of strong mass segregation and loss-cone refilling by massive perturbers and resonant relaxation; describe observational evidence that these processes play a role in the Galactic Center and can be studied there; and discuss some of the implications for Extreme Mass Ration Inspiral event rates and their properties.
