Abstract
It is expected that about 10^8 isolated black holes (IBH) produced by stellar evolution populate the Galaxy. These objects are expected to accrete from the medium, subsequently producing winds, thermal emission, and potentially, jets and non-thermal energetic radiation. The aim of this project is to estimate the number of IBH that could fill the densest regions of the Galaxy, and explore whether relatively
nearby objects could be detectable from the Earth. As dense environments make detection difficult due to absorption, only the most energetic non-thermal emission will be considered.
