Abstract
A calculation is presented of X-ray emission from the disk and radio h alo of the starburst galaxy NGC 253. Compton scattering of the radio e mitting electrons off the far-infrared radiation field in the halo of this galaxy can account for the 50-200 keV emission recently detected by OSSE. This could possibly be the first detection of diffuse Compton emission from a galaxy which is not a bona fide active galactic nucle us.
