Metallicity Effects on Dust Properties in Starbursting Galaxies
Metallicity Effects on Dust Properties in Starbursting Galaxies
We present infrared observations of 66 starburst galaxies over a wide range of oxygen abundances, to measure how metallicity affects their dust properties. The data include imaging and spectroscopy from the Spitzer Space Telescope, supplemented by groundbased near-infrared imaging. We confirm a strong correlation of aromatic emission with metallicity, with …
