Metals from star-forming dwarfs: retention or ejection?
We show evidences that gas outflows occur in starburst galaxies as superbubbles evolve. We then question whether hot gas will be expelled and enrich the IGM with metals or be retained within the host galaxy. For this purpose we construct three extreme scenarios of the star formation histories for a sample of dwarf galaxies using either their
