Early-type Galaxies in Isolation: an HI Perspective with ATLAS 3D
We present preliminary results of our HI WSRT observations of early-type galaxies in the ATLAS3D sample. We discuss the dependence of HI properties on environment. We detect HI in about half of the galaxies outside the Virgo cluster. The HI morphology/kinematics changes as a function of environment, going from regular, rotating systems around
