A Long Period Stellar-Mass Black Hole Binary in Centauri
Matthew Whitaker, Evan Kerr, Anil Seth +16
Modern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited. We pr…

OGLE-2011-BLG-0462: An Isolated Stellar-Mass Black Hole Confirmed Using New HST Astrometry and Updated Photometry
Kailash C Sahu, Jay Anderson, Stefano Casertano +7
The long-duration Galactic-bulge microlensing event OGLE-2011-BLG-0462 produced relativistic astrometric deflections of the source star, which we measured using HST observations ta…

Fast-moving stars around an intermediate-mass black hole in Omega Centauri
Maximilian Häberle, Nadine Neumayer, Anil Seth +15
Black holes have been found over a wide range of masses, from stellar remnants with masses of 5-150 solar masses (Msun), to those found at the centers of galaxies with Msu…
