We discuss the possibility that the recent detection of 511 keV γ-rays from the galactic bulge, as observed by INTEGRAL, is a consequence of low mass (∼MeV) particle dark matter annihilations. We discuss the type of halo profile favored by the observations as well as the size of the annihilation cross section needed to account for the signal. We find that such a scenario is consistent with the ...

During its first cycle, the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope was performing an observational campaign covering a total of about 250 hours on galactic sources. Here we review the results for the very high energy (> 100 GeV) γ-ray emission from some of those sources.

We present a measurement of the microlensing optical depth toward the Galactic Bulge based on 4 years of OGLE-II survey. We consider only bright sources in the extended Red Clump Giant (RCG) region of the Color-Magnitude

The primary objective of the study of unidentified EGRET sources with INTEGRAL is to locate with a few arcminute accuracy the hard X-ray / soft γ-ray counterparts within the EGRET error circle or to determine upper limits on their emission in the INTEGRAL energy range. The INTEGRAL Galactic Plane Scan (GPS) and Galactic Centre Deep Exposure (GCDE) data have been analysed and cross–correlated wi...
