On the Possibility of Direct Detection of the Emission of Microlens MOA-2011-BLG-191/OGLE-2011-BLG-0462—a Probable Black Hole

Description
Summary:— We discuss the observational manifestations of an isolated stellar mass black hole—the recently discovered microlens MOA-2011-BLG-191/OGLE-2011-BLG-0462. The data available for this object are used to calculate the density, temperature, and sound speed in its local interstellar medium, as well as estimate its velocity. We obtain the accretion rate and luminosity of the object, and construct its theoretical spectrum. A comparison of the spectrum with the sensitivity levels of current and future instruments in different frequency ranges has shown that direct detection of the emission from this black hole is possible for several future observing missions.
