Starbursts And Their Consequences: The Case Of NGC 1569

In the gas-rich irregular dwarf galaxy NGC 1569, much evidence can be found that this galaxy has recently undergone a strong starburst: A distinct kink in the non-thermal radio spectrum reflects the ageing of the relativistic electrons and thus an end of the starburst period about 5 million years ago (Israel and de Bruyn, 1988). Photometric studies have yielded high past star formation rates of up to 3 M⊙/yr from 100 to 4 million years ago (Vallenari and Bomans, 1996). And at the position of two very bright super-star clusters, hot, X-ray emitting plasma has been found, that is likely to blow out of the galaxy (e.g. Martin, 1999).
