The Metal Content of Dwarf Starburst Winds: Results from<i>Chandra</i>Observations of NGC 1569

Abstract

(Abridged) We present deep, Chandra spectral imaging of the dwarf starburst galaxy NGC 1569. The unprecedented spatial resolution allows us to spatially identify the components of the integrated \x spectrum. Fitted spectral models require an intrinsic absorption component and higher metal abundances than previous studies indicated. Our results provide the first direct evidence for metal-enriched winds from dwarf starburst galaxies.
