Colloquium

Colloquium by Eilat Glikman

The study of the evolution of quasars and their influence on their host galaxies provides unique insight into how supermassive black holes became a ubiquitous feature of galaxies today. Dust-reddened quasars appear to represent a transitional phase in merger-driven models of quasar/galaxy co-evolution. I will present results from recent and ongoing surveys to identify these transitional systems using infrared and radio selection. The results of these surveys reveal that red quasars are among the most intrinsically-luminous quasars in the Universe, and make up ~20% of the overall quasar population. They reside in actively merging galaxies, and their rest-frame UV spectra exhibit outflows in absorption and emission. I will discuss how reddened quasars fit into the larger picture of AGN evolution which includes both mergers and secular growth. Finally, I will present new work on surveys designed to explore the red-quasar parameter space to fully understand the connection between galaxy mergers and black hole growth.

Followed by wine and cheese in Pupin 1332.
