Please join the Lowell Center for Space Science and Technology for the virtual talk "Cosmological Evolution of Supermassive Black Holes" by Prof. Suchetana Chatterjee on Thursday, Nov. 7 from 11 a.m. to noon.

Abstract
It is now believed that every galaxy in the universe harbors a supermassive black hole (SMBH) (a million to a billion solar masses) at their centers. Multi-wavelength observations confirmed the role of SMBH in the overall evolution of their host galaxies. A small fraction of these SMBHs harbor an active accretion disk around them and emit radiation spanning the entire electromagnetic spectrum. The flux from these central regions overwhelms the emission from the entire galaxy, making them detectable at very high redshifts. These special classes of galaxies are known as active galactic nuclei (AGN). The interplay between the AGN and their host galaxies is known as the AGN co-evolution paradigm. In this talk, I shall throw light on the AGN co-evolution paradigm through the usage of multi-wavelength data and theoretical modeling.
