AGN反馈的大图像:多波长巡天中的黑洞吸积和星系演化

The big picture of AGN feedback: Black hole accretion and galaxy evolution in multiwavelength surveys

Ryan C. Hickox

摘要:

大规模的河外巡天观测使我们能够在统计意义上追踪超大质量黑洞、它们的宿主星系以及它们的暗物质晕在宇宙时间内是如何一起演化的,从而探索活动星系核反馈对星系演化的影响。最近的研究发现,黑洞的吸积状态与星系恒星星族、局部环境以及气体和尘埃的遮蔽之间存在着重要的联系。本文介绍了一些最近的结果,并显示这些研究可能会提供新的约束模型的星系和中央SMBHs的共同演化。最后,我讨论了拟议的宽视场X射线望远镜任务的观测前景。

英文摘要:

Large extragalactic surveys allow us to trace, in a statistical sense, how supermassive black holes, their host galaxies, and their dark matter halos evolve together over cosmic time, and so explore the consequences of AGN feedback on galaxy evolution. Recent studies have found significant links between the accretion states of black holes and galaxy stellar populations, local environments, and obscuration by gas and dust. This article describes some recent results and shows how such studies may provide new constraints on models of the co-evolution of galaxies and their central SMBHs. Finally, I discuss observational prospects for the proposed Wide-Field X-ray Telescope mission.
