HST Detection of Extended Neutral Hydrogen in a Massive Elliptical at z = 0.4

Fakhri S. Zahedy, Hsiao-Wen Chen, Michael Rauch +1

We report the first detection of extended neutral hydrogen (HI) gas in the interstellar medium (ISM) of a massive elliptical galaxy beyond z~0. The observations utilize the doubly…
