Abstract:

Our talk will deal with the population of unresolved millisecond pulsars which have been shown to likely explain the putative GeV gamma ray excess at the galactic center. We critically analyze the spectral properties of few candidate unassociated sources, looking in particular for correlations in the radio catalogs. Our main goal is to study the potentials for detection of these source population in radio and X-rays through current and upcoming missions, in the effort to establish the true nature of the gamma-ray photons detected at the galactic center.
