Abstract
We performed a search for stellar-mass black hole (BH) candidates in the birth regions of 4
pulsars. We analyzed the available spectral, photometric and astrometric data to isolate 8 objects
that exhibit characteristics corresponding to theoretical predictions for isolated BHs. We also
discuss the observational manifestations of a stellar mass BH - the recently discovered microlens
MOA-2011-BLG-191/OGLE-2011-BLG-0462. The data available for this object are used to
calculate the parameters of its local interstellar medium, obtain the accretion rate and luminosity
of the object, and construct its theoretical spectrum. A comparison of the spectrum with the
sensitivity levels of several instruments shows that direct detection of the emission from this BH
is possible for several future observing missions.
