Extended ionized gas discs in lenticular galaxies: imprints of external accretion

The 3D-spectroscopy technique is used to study the origin of gas in early-type galaxies possessing extended (more than a few kpc in size) ionized-gas discs. Analysis of the ionized gas velocity fields derived from scanning Fabry-Perot interferometer observations at the SAO RAS 6-m telescope together with the available kinematic map of the central regions (MPFS, SAURON, and CALIFA data) and of the external HI gas behaviours provides evidences for gas accretion from outside in the most of the observed objects. The value of gas/stars misalignment varies significantly with radii on a scale of a few kpc. Gas accretion footprints are present in different environments: from rich groups to quite isolated galaxies.
