We present here a computer model of the spatial distribution of the luminosity, produced by old isolated neutron stars and black holes accreting from the interstellar medium. We show that the luminosity distributions in the Galaxy have a ring structure, with a maximum at [FORMULA] radius.

Key words: stars: neutron – black hole physics – Galaxy: stellar content
