Scientific paper

In this talk I argue that dark matter in the form of dense matter/antimatter nuggets could provide a natural and unified explanation for several distinct bands of diffuse radiation from the core of the galaxy spanning over 13 orders of magnitude in frequency. It includes: SPI/INTEGRAL observations of 511 keV gamma rays; detection by the CHANDRA satellite of diffuse X-ray emission; COMPTEL observation of the flux of gamma rays in the 1-20 MeV range; finally, the so-called "WMAP- haze" which is a diffuse microwave excess observed from the core of our galaxy. If correct, our proposal identifies the nature of the dark matter, explains baryogenesis, and provides a means to directly probe the matter distribution in our Galaxy by analyzing several different types of diffuse emissions.
