The quasar-galaxy connection: outflow properties of luminous quasars

现代天体物理学的主要目标之一是获得与中央超大质量黑洞及其宿主星系之间的假定物理联系有关的直接观测证据。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会逃离中心超大质量黑洞的引力势，并对宿主星系产生重大影响。该博士项目将开始通过考虑与发光类星体相关的流出物质的性质的限制，结合证据从a）宽吸收线，B）窄吸收线和c）发射材料明显的类星体光谱能量分布。一个初步的目标将是确定是否流出的发光类星体的属性与物理参数负责吸积光度。博士学位的后续工作计划将取决于初步调查的结果和Amy Rankine的兴趣。

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.
