摘要:

理解驱动星系形成和塑造星系观测特性的过程是现代天体物理学最有趣和最具挑战性的前沿问题之一。我们现在知道星系的演化是由吸积超大质量黑洞(SMBHs)的能量注入决定的。然而,目前还不清楚这种反馈过程的物理学究竟如何影响星系形成和演化。特别是,一个主要的挑战是解开SMBH附近释放的能量如何分布在整个星系及其周围环境的9个数量级的距离上。研究SMBH反馈影响的最佳地点是大质量星系、星系团和星系团的热大气层,这些星系团拥有宇宙中最大的黑洞,在那里我们可以直接成像黑洞对其周围环境的影响。我们确定了关键问题和潜在的测量,这可能会改变我们对SMBH反馈物理学的理解,以及它如何塑造星系,通过详细测量(i)团内介质(ICM)中的热力学和速度波动以及(ii)星系团中心SMBH膨胀的气泡成分,以及它们对星系团气体和星系生长的影响,使用下一代高光谱和空间分辨率的X射线和微波望远镜。

英文摘要:

Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern astrophysics. We now know that the evolution of galaxies is critically shaped by the energy injection from accreting supermassive black holes (SMBHs). However, it is unclear how exactly the physics of this feedback process affects galaxy formation and evolution. In particular, a major challenge is unraveling how the energy released near the SMBHs is distributed over nine orders of magnitude in distance throughout galaxies and their immediate environments. The best place to study the impact of SMBH feedback is in the hot atmospheres of massive galaxies, groups, and galaxy clusters, which host the most massive black holes in the Universe, and where we can directly image the impact of black holes on their surroundings. We identify critical questions and potential measurements that will likely transform our understanding of the physics of SMBH feedback and how it shapes galaxies, through detailed measurements of (i) the thermodynamic and velocity fluctuations in the intracluster medium (ICM) as well as (ii) the composition of the bubbles inflated by SMBHs in the centers of galaxy clusters, and their influence on the cluster gas and galaxy growth, using the next generation of high spectral and spatial resolution X-ray and microwave telescopes.
