Physics Colloquium with Charles Gammie on Portrait of a Black Hole

The Event Horizon Telescope images of M87* and Sgr A* have opened a new era of resolved imaging of black holes at the event horizon scale.  I will describe how EHT measurements are made, how they can be interpreted with the aid of state-of-the-art models, what they teach us about black holes, and what the prospects are for future experiments.

Charles Gammie is Professor of Astronomy and Willett Chair in Physics at the University of Illinois.  He received a PhD from Princeton in 1992, was a postdoc at the University of Virginia and the Center for Astrophysics, and has been a faculty member at Illinois since 1999.
