Detection of diffuse high energy X-ray and γ-ray emission from starburst galaxies and clusters of galaxies will significantly advance the study of these systems. We review the results of OSSE observations of the nearby starbursts NGC 253 and M82. Compton scattering of relativistic electrons by the far IR and cosmic microwave background radiation fields can account for the observed emission from NGC 253. The predicted level of this emission in M82 is close to the upper limit set by OSSE. Based on OSSE and recent ISO observations of ultraluminous IR galaxies, including Arp 220, it can be inferred that these galaxies are powered largely by starburst activity. Nonthermal emission has not yet been detected from clusters, including the Coma cluster which was the target of a two-week OSSE observation. We review current lower limits on intracluster magnetic fields and upper limits on relativistic electron energy densities in the clusters already observed at high energies. Improved spectra of NGC 253, M82, and the Coma cluster are expected soon from recent observations of these systems by the PCA and HEXTE experiments aboard the RXTE satellite.
