Detecting black hole occultations by stars with space interferometric telescopes.

CHRISTIAN P. and LOEB A.

Abstract (from CDS):

We show that the occultation of Sagittarius A* by stars can be detected with space-based or space-ground very-long-baseline interferometers, with an expected event rate that is high due to relativistic precession. We compute the tell-tale signal of an occultation event and describe methods to flag nonoccultation events that can masquerade as the signal.
