Astrophysics Lectures - Observing Black Holes - Marianne Heida - 09/06/2019

What does a black hole look like? We now know, and have observed black holes in multiple ways. Measuring black hole properties gives us insight into the stars they came from and the galaxies they reside in.

How do you observe something that doesn't emit any light? The first picture of the shadow of a black hole was only taken this year, but astronomers have been studying them for decades through the effect they have on their surroundings. In this lecture we will go over the many methods astronomers use to search for and investigate the properties of black holes of all kinds, from the small ones in our cosmic backyard to the monsters in the centers of galaxies.
