PROJECT TITLE: Mass and spin evolution of supermassive black holes: constraints from multi-wavelength observations of QSOs and AGNs

PROJECT DESCRIPTION: It is widely accepted that supermassive black holes co-evolve with their host galaxies. This co-evolution includes a number of important physical processes, such as disk accretion onto supermassive black holes, feedback from nuclear activities, and mergers of supermassive binary black holes, etc. The goal of this project is to investigate the mass and spin evolution of supermassive black holes in galactic centers, by theoretically modeling the multi-wavelength observations of individual QSOs/AGNs and the total population and various sub-population of QSOs/AGNs in-cooperating those physical processes.

PROJECT REQUIREMENTS: General familiarity with black hole physics, extra-galactic astronomy, and cosmology. Expertise in modeling of disk accretion onto massive black holes, and numerical simulations of mergers of galaxies and their central massive black holes, semi-analytical modeling of the formation and evolution of galaxies.
