X-ray Properties of Young Early Type Galaxies: II. Abundance Ratio in the Hot ISM
, 2011 Using Chandra X-ray observations of young, post-merger elliptical galaxies, we present X-ray characteristics of age-related observational results, by comparing with typical old elliptical galaxies in terms of metal abundances in the hot interstellar matter (ISM).
