Abstract

Gravitational microlensing is the only technique allowing for detecting individual and non-interacting stellar remnants, in particular neutron stars and black holes. I will present candidates for stellar remnant microlenses found in the decade-long photometric monitoring of hundred million stars towards the Galactic Bulge by the Polish OGLE project. I will show how combining photometry from OGLE and astrometry from Gaia mission will ultimately solve the uncertainties in the mass measurements of stellar remnants.
