DeVaucouleurs Medalist

Public Lecture: "Black Holes, Galaxies and the Evolution of the Universe: An Observer's View"

Black holes form in the young Universe and, over the next 13 billion years or so, accrete enormous amounts of matter from the surrounding galaxy. By the present time, a black hole and its host galaxy have grown in mass by factors of a million or more, roughly in lockstep. In this talk, I will first give several alternative descriptions of what a black hole is, then explain how recent multiwavelength surveys have allowed us to take a census of black hole growth across cosmic time. I conclude with the big picture: the evolution of the universe over the last 13 billion years, as indicated by computer simulations, and future prospects for observing black hole growth and mergers across the cosmos.
