摘要
We consider a dark matter model with "active" component (annihilating or decaying), that forms a disk in the Galaxy. In this work we calculate gamma-ray flux from the galactic center for given model and compare it to the observations. It was found that predicted flux with model parameters obtained in our last analysis which did not take the data on gamma-ray flux from the center into account, agrees (does not exceed) observational one. Gamma-ray fluxes for the whole sky have been obtained and compared with existing data. Unfortunately existing data include contributions from all possible gamma-ray sources in a wide energy range, what requires respective special analysis. We adopted existing data in a simple way to compare with them and obtained qualitative agreement.
