Scientific paper

The suggestion (Sciama 1989) that the dark matter in the Galaxy decays into hydrogen-ionizing photons at a rate sufficient to account for some otherwise unexplained properties of the galactic ionized gas is investigated. According to this suggestion, the galactocentric radial distribution of free electrons, which has previously been derived from pulsar dispersion measure data, yields directly the radial distribution of dark matter. This derived distribution leads to a galactic mass model which is in excellent agreement with observations.
