Coronal Electron Scattering of Hot Spot Emission Around Black Holes

Massachusetts Institute of Technology, Cambridge, MA 02139, USAUsing a Monte Carlo ray-tracing code in full general relativity, we calculate the transport ofphotons from a geodesic hot spot emitter through a corona of hot electrons surrounding a blackhole. Each photon is followed until it is either captured by the black hole or is detected by a distantobserver. The source is assumed to be a low-energy thermal emitter (T
