Feeding the faintest black holes: the nature of low-luminosity accretion

绝大多数黑洞都处于极其微弱的静止状态。该项目旨在提高对大量黑洞的理解，确定流入气体的几何形状，微弱x射线发射的来源，以及快速移动的射流向外泵送的能量的比例。在最近突破性成果的基础上，该项目旨在开展一项调查，以探测密集星团中的新黑洞群，为探索吸积物理学提供新的实验室。它旨在测量黑洞的距离及其在空间中的运动，测试视界存在的证据，并为黑洞如何形成以及它们如何影响周围环境提供新的见解。

The overwhelming majority of black holes are found in an extremely faint quiescent state. This project aims to improve understandings of this large population of black holes, determining the geometry of the inflowing gas, the source of the faint X-ray emission, and the fraction of energy pumped outwards in fast-moving jets. Building on recent ground-breaking results, this project aims to conduct a survey to detect a new population of black holes in dense star clusters, providing new laboratories to explore accretion physics. It aims to measure the distances of the black holes and their motion through space, test evidence for the existence of event horizons, and provide new insights into how black holes form and how they affect their surroundings.
