Numerical Models of Black Hole Accretion Flows

Charles Gammie ( University of Illinois at Urbana-Champaign ) - February 25 at 12:00 noon

Quasars, AGN, galactic black hole binaries, and gamma ray bursts are all probably powered by a rotating black hole surrounded by a magnetized plasma. I will describe recent fully relativistic, time-dependent numerical models of these systems. I will compare the numerical results with analytic models, such as the Blandford-Znajek force-free magnetosphere, and describe how the black hole exchanges energy and angular momentum with the surrounding plasma.

The seminar will be held in 501 Campbell Hall.
