Obtaining direct observational evidence that relates to the postulated physical link between central supermassive black holes and their host galaxies is one of the major goals of modern astrophysics. A key question is whether the outflowing material, that is associated with a large fraction of luminous quasars, escapes the gravitational potential of the central supermassive black hole and has a significant impact on the host galaxy. The PhD project will begin by considering the constraints on the properties of outflowing material associated with luminous quasars by combining evidence from a) broad absorption lines, b) narrow absorption lines and c) emitting material evident in the quasar spectral energy distribution. An initial goal will be to establish whether the outflow properties of luminous quasars are related to the physical parameters responsible for the accretion luminosity. The subsequent work plan for the PhD will depend on the results of the initial investigation and Amy Rankine's interests.

获得与中心超大质量黑洞与其宿主星系之间假定的物理联系相关的直接观测证据是现代天体物理学的主要目标之一。一个关键问题是，与大部分发光类星体相关的流出物质是否逃脱了中心超大质量黑洞的引力势，并对宿主星系产生重大影响。该博士项目将首先考虑与发光类星体相关的流出材料特性的限制，结合来自a）宽吸收线、b）窄吸收线和c）类星体光谱能量分布中明显的发射材料的证据。最初的目标是确定发光类星体的流出特性是否与负责吸积光度的物理参数有关。随后的博士工作计划将取决于初步调查的结果和艾米·兰金的兴趣。
