The High Energy Gamma-Ray Background as a Probe of the Dark Matter in the Galactic Halo | R. Chary

20 Nov 1998 | Subject: | astro-ph | Abstract: | We present constraints on the density of halo dark matter candidates within the solar circle based on the anisotropy in the high energy gamma-ray background. The known galactic components of the gamma-ray background, in particular the inverse Compton component, have been estimated more accurately. We find the spectrum of the residual emission, after subtracting the galactic component is inconsistent with emission from some of the proposed dark matter candidates. We derive upper limits of 10^8 M_sun for the mass of diffuse gas and 3*10^9 pc^(-3) for the number density of primordial black holes contributing to the gamma-ray background. | Source: | arXiv, astro-ph/9811324 | Services: | Forum | Review | PDF | Favorites |
