Multiwavelength Insights Into Supermassive Black Hole Growth Across Cosmic Time

Abstract

===========================================

Shining brighter than a trillion Suns, quasars are the most powerful persistent sources in the universe. As such, they serve as cosmic signposts, shedding light on the formation of cosmic structure. It is now widely accepted that their energy is produced by accretion of matter onto a supermassive black hole (SMBH) in the center of their host galaxy. However, in spite of several decades of quasar research it is not yet clear how SMBHs formed and have grown through cosmic time, how they regulate the properties of their host galaxies, or what is their accretion duty cycle. I will present a summary of key multiwavelength observational efforts I have been pursuing at UNT that provided crucial insights into 1) SMBH growth in galactic centers, 2) the accretion process, and 3) the quasar-host galaxy feedback mechanism.
