  Title: SUPERWINDS IN STARBURST GALAXIES: NGC2146 AND 7552                              


Abstract:
 Supernova-driven mass outflows have been proposed to have profound effects on the
 formation and evolution of galaxies and on the enriching and energizing of the IGM.
 X-ray data provide unique insight into the superwind phenomenon because X-rays come
 directly from the wind material as well as shock-heated clouds and swept-up ambient
 ISM. We propose ASCA observations of two nearby starburst galaxies selected from the
 IRAS catalog, NGC 2146 and NGC 7552, for which we have strong evidence for outflows.
 The ASCA hard X-ray data will be of fundamental importance to discriminate between
 (i) very hot shock-heated plasma with Fe XXV emission lines and (ii) the combined emission of massive X-ray binaries.
