Abstract
It is shown that dark matter forms a halo around the galaxy. The size of the halo and the moment of its formation are respectively estimated to be R0=300-400 kpc and Z0=5-7. The same halo is formed by relic neu tron stars (RNS) occurring in the protogalaxy as a result of supernova bursts which cause a change in the original chemical composition. The second component of the neutron stars, which were born in the galacti c disk and were pulsars at the early stage of their evolution, occurs much later. The statistic distribution of gamma-bursts determined by b oth neutron-star components is shown to be in good agreement with obse rvations. A method of direct verification of the model is proposed.
