dc.descriptionWe expand on the recently reported detections of the gamma-ray resonant absorption along the line of sight toward gamma-ray bright quasars (QSOs), like 3C279. We propose to use this novel gamma-ray absorption method to study the Dark Matter distribution in the Milky Way, as well as in the Local Group. Properties of the absorber that was detected on the sight lines towards gamma-ray bright QSOs at zero redshift are discussed. We compare our results with the expected Dark Matter distributions in the halo of Milky Way, that were simulated in boundaries of different CDM models. Application of this new method to study evolution of CDM in the QSO host galaxies, and of baryons distribution in the halo of galaxies in the Local Universe is proposed.
