The Hot Interstellar Medium of Normal Elliptical Galaxies. I. A<i>Chandra</i>Gas Gallery and Comparison of X‐Ray and Optical Morphology

We present an X-ray analysis of 54 normal elliptical galaxies in the Chandra archive and isolate their hot gas component from the contaminating point-source emission, allowing us to conduct, for the first time, a morphological analysis on the gas alone. A comparison with optical images and photometry shows that the …
