Quasars: the Brightest Black Holes - Professor Carolin Crawford
Quasars are among the most dramatic objects anywhere in the cosmos. They emit prodigious amounts of energy, all due to a supermassive black hole at the heart of a galaxy. Visible far across the Universe, quasars can be used to trace both the early life of galaxies, and the properties of the intervening space. (from gresham.ac.uk)
