Descripción
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
“isolated” galaxies to progressively more disturbed
structures for galaxies with neighbours or in groups. In denser
environment, inside Virgo, nearly none of the galaxies contains HI.
