Self-Similar Models of Quasar Outflow Shock Structures
Supersonic winds of outflowing material are observed and/or predicted in a number of astrophysical systems; such winds may drive an expanding shock structure that shocks and pushes the ambient interstellar medium (ISM) outward. This thesis analyses, combines and expands on existing analytic …

Outflows and Dust in Quasars
… so-called `active galactic nuclei' (AGN) or `quasars'. These AGN are believed to feed back energy into their host galaxies, regulating star formation and the growth of the SMBH itself. This thesis investigates the outflow properties in quasars at 1<z<3, corresponding to the peak epoch of …

On the Distances and Energetics of AGN Outflows
Active galactic nuclei (AGN) ubiquitously show outflows. It is now widely recognized that these outflows are key components in the evolution of super-massive black holes and their host galaxies. As important as these outflows are, we still lack sufficient understanding of their structure and …

How Do Quasars Impact Their Host Galaxies? From the Studies of Quasar Outflows in Absorption and Emission
"Quasar-mode feedback" occurs when momentum and energy from the environment of accreting supermassive black hole couple to the host galaxy. One mechanism for such a coupling is by high-velocity (up to ~0.2c) quasar-driven ionized outflows, appearing as blue-shifted absorption and emission lines in …
