This is a subject that Dr. Brandt spends much research time on. He is an X-ray astronomer and studies the giant black holes that we think powers quasars and active galaxies. Start by telling you what a quasar is and then we'll talk about the history of them and how they were discovered and our theories for how they work. Then we'll talk about active galaxies in general. Quasar - most luminous type of object in the Universe.
Light comes from a very small point and looks like a star.
