Astrophysical black holes are simultaneously exotic and robust predictions of classical general relativity, the sites of numerous high-energy phenomena, mechanisms coupling the small and large scales of the Universe, and an object of considerable controversy in efforts to develop a unified quantum theory. Advances in the availability of large-scale computing, the recent development of a global array of mm-wave radio telescopes capable of resolving the event horizons of nearby supermassive black holes, tantalizing hints of a new class of black holes that bridge the gap between the stellar and supermassive varieties, and the renewed cosmological importance of supermassive black holes both enable and motivate novel efforts to address outstanding questions in black hole science. Among these are "Do black holes exist?", "Does general relativity provide an accurate description of gravity in the vicinity of the horizon", "How do they interact with their immediate environments?", and "What impact do they have upon the Universe on cosmological scales?" These are inextricably linked; the emission and outflows from active galactic nuclei that figure prominently in galactic and extra-galactic scales are powered and launched by events near the central black hole's horizon, and conversely, the rate at which black holes accrete matter is dictated by both the supply available on galactic scales and the physics of the accretion process. My primary focus is identifying ways to bring new and emerging observational and theoretical techniques to bear upon these fundamental questions on all scales.

天体物理学黑洞是经典广义相对论的奇异和强有力的预言，是许多高能现象的场所，是耦合宇宙大小尺度的机制，也是发展统一量子理论的一个相当有争议的对象。 大规模计算的可用性方面的进展，最近开发的全球毫米波射电望远镜阵列能够分辨附近超大质量黑洞的事件视界，一种新的黑洞类别的诱人暗示，它弥合了恒星和超大质量黑洞之间的差距，以及超大质量黑洞在宇宙学上的新的重要性，都使人们能够并激励人们做出新的努力来解决黑洞科学中悬而未决的问题。 其中包括“黑洞存在吗？“，“广义相对论是否提供了视界附近引力的精确描述”，“它们如何与周围环境相互作用？和“在宇宙学尺度上它们对宇宙有什么影响？“这些是密不可分的;在银河系和河外尺度上突出的活动星系核的发射和流出是由中央黑洞视界附近的事件提供动力和发射的，相反，黑洞吸积物质的速率取决于星系尺度上可用的供应和吸积过程的物理学。 我的主要重点是确定如何将新的和新兴的观测和理论技术在所有尺度上对这些基本问题产生影响。
