A black hole is a region of spacetime from which no particles or even electromagnetic radiation can escape, because of the strong gravitational field. Black holes are astrophysical objects that can be formed through various scenarios, for example they are the ultimate fate of extremely massive stars. I am working on the shadow of spinning black hole and on the interplay between dark matter and black holes.
The Event Horizon Telescope (EHT) collaboration has recently released the first image of a black hole (BH), opening a new window onto tests of general relativity in the strong field regime. In this paper, we derive constraints on the nature of M87* (the supermassive object at the center of the galaxy M87), exploiting the fact that its shadow appears to be highly circular, and using measurements of its angular size.
