MACHOs and the diffuse X-ray background
Abstract
The possible contribution of X-ray emission from massive compact objects in the Galactic halo (MACHOs) to the diffuse X-ray background is explored. We show that such emission cannot be responsible for the shadowing seen in soft X-ray observations by ROSAT but that these objects may indeed contribute significantly (at levels greater than 10%) to the diffuse background at higher (greater than or approximately 0.5 keV) energies. Thus, X-ray observations may well be able to significantly constrain the spatial distribution of MACHOs.
