Title:  Imaging an Event Horizon

The galactic center black hole, Sagittarius A*, has the largest angular size of any known black hole. This makes it the best candidate for direct imaging of an event horizon. We have computed the appearance of accreting black holes for a variety of simple models, and show that the event horizon casts a shadow, causing a dip in the emission. Future VLBI experiments at sub-mm wavelengths should be able to detect this shadow, which would be the ultimate test of the existence of a black hole.
