A<i>Chandra</i>Survey of Early‐Type Galaxies. I. Metal Enrichment in the Interstellar Medium
We present the first in a series of papers studying the X-ray properties of 28 early type galaxies spanning ~3 orders of magnitude in L_x. We report emission-weighted constraints for Fe, O, Ne, Mg, Si, S and Ni. We find no evidence of the very sub-solar Z_Fe historically reported, confirming …
