Abstract
The paper presents a model of nonthermal electromagnetic emission from superbubbles (SBs) surrounding OB associations. We predict that the s ources have flat radio spectrum with a knee at a few GHz, and hard spe ctrum of X- and gamma-rays with luminosity of the order of 10(35) erg s-1. We conclude that SBs represent a new population of nonthermal sou rces.
