Abstract:
In the past few years, it has become possible to image black holes. Long baseline interferometry experiments operating at millimeter and near-infrared wavelengths can now achieve event horizon scale angular resolution with sufficient sensitivity to detect synchrotron radiation from hot plasma near the Galactic center black hole, Sgr A*, and the supermassive black hole in M87. I will discuss major results from each experiment, and focus on our group's work using the data to study accretion physics and particle acceleration in the immediate vicinity of an event horizon.
