Abstract

We compute the synthetic 2-100 keV spectrum of an actively star forming galaxy. To this aim we use a luminosity function of point sources appropriate for starbursts (based on Chandra data), as well as the types of stellar sources and their corresponding spectra. Our estimates indicate that a Compton spectral component - resulting from scattering of SN-accelerated electrons by ambient FIR and CMB photons - could possibly be detected, in deep INTEGRAL observations of nearby starburst galaxies, only if there is a break in the spectra of the brightest (L ≥ 2 × 10³⁸ erg s^-1) point sources.
