Supermassive (double) black hole tidal disintegration event

Xinwen Shu Seminar


Abstract

The co-evolution of galaxies and black holes implies that there is a black hole in the center of almost every massive galaxy. According to the existing evolutionary theory of hierarchical clustered galaxies, there should be a large number of supermassive double black hole systems in the universe. However, even after more than 30 years of research, astronomers have found supermassive double black holes in only a few active galaxies. This report will introduce how to use the tidal tearing star event to detect and study the dormant black hole and its gas environment in the quiet galaxy that accounts for the majority of the universe. At the same time, it will report on the latest research progress in this field, including the discovery of supermassive dormant double black holes that swallow stars. __________
