Spinning Black Holes

The video explores tidal disruption events, where a star is consumed by a supermassive black hole, forming an accretion disk. Observations revealed periodic x-ray pulses, leading to insights about black hole spin. The video explains how spin is measured using rISCO and its implications for understanding black hole growth and galaxy formation.
