AGN闪烁与混沌吸积

AGN Flickering and Chaotic Accretion

Andrew King, Chris Nixon

摘要:

观测结果表明,活动星系核中超大质量黑洞的生长阶段具有特征性的时间尺度$\sim 10^5$ yr。我们表明,这是预期的时间尺度在混沌吸积图片的黑洞喂养,因为自引力的影响,限制任何吸积盘喂养事件的质量。

英文摘要:

Observational arguments suggest that the growth phases of the supermassive black holes in active galactic nuclei have a characteristic timescale $\sim 10^5$ yr. We show that this is the timescale expected in the chaotic accretion picture of black hole feeding, because of the effect of self-gravity in limiting the mass of any accretion disc feeding event.
