Title: Astrophysical Evidence for the Black Hole Event Horizon


Astronomers have discovered many candidate black holes in X-ray binaries
and in the nuclei of galaxies. While the evidence
that these objects are black holes is strong, there is no proof yet that
the objects actually possess event horizons. The talk will
describe some of our recent efforts to find such proof.
