The quasar-galaxy connection: outflow properties of luminous quasars
Lead Research Organisation:
University of Cambridge
Department Name: Institute of Astronomy
Abstract
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.

Results and Impact | The Institute of Astronomy opens its doors each year to the public to share the research that goes on in the department. Volunteers are requested to create and run activities throughout the day for a range of age groups. I created, along with two others, an Astronomy Guess Who aimed at 5-11 year olds where they have to work out which type of galaxy their opponent has chosen by asking questions about the shape and the colour of the galaxy. It is always a success with a few hundred people passing through each year. |
