星系核-黑洞的共同演化、活动星系核的反馈和供养

Galactic bulge-black hole co-evolution, feeding and feedback of AGNs

Francoise Combes

摘要:

自20世纪90年代以来,我们已经知道每个星系中都有一个超大质量的黑洞,它的质量与凸起的质量成正比。为了更好地理解这些黑洞是如何形成的,与它们的星系共生,我们将研究它们的人口统计学,黑洞和宿主星系之间的比例关系,以及它们在哈勃时间内的演化。高角分辨率的观测现在使我们能够进入黑洞的影响范围,看到活动星系核统一范式中引发的分子环面,并了解黑洞的进食过程。这些通常伴随着反馈过程,这缓和了星系的形成。这是一篇研究生水平的演讲,而不是一篇评论文章。

英文摘要:

Since the 1990s, we have known that there is a super-massive black hole in every galaxy, and that its mass is proportional to the mass of the bulge. To better understand how these black holes were formed, in symbiosis with their galaxies, we will look at their demography, the scaling relations between properties of black holes and host galaxies, and their evolution in a Hubble time. Observations at high angular resolution now allow us to enter the black hole sphere of influence, to see the molecular tori evoked in the AGN unification paradigm, and to understand the feeding processes of black holes. These are often accompanied by feedback processes, which moderate the formation of galaxies. This is a graduate-student level lecture, not a review article.
