Black holes are well-known celestial bodies that are often featured in popular films and fictions. Usually portrayed as a black lobe sucking in everything around it, black hole is one of the most menacing and mysterious things out there in the universe. However, black holes do not devour everything – matters attracted by its gravity can orbit around it at high speed, producing blindingly bright radiations; this is known as the accretion disk of black holes. Dr William Alston’s research focuses on the analysis of accreting black holes, and he is going to give an overview of these sources and the methods astrophysicists use to study these environments and what physics they are trying to understand.
