Description
We present a summary of high-spatial resolution follow-up observations
of the elliptical (E) and lenticular (S0) galaxies in the SAURON survey
using the OASIS integral field spectrograph. The OASIS/observations
explore the central 8″×10″ regions of these galaxies
using a spatial sampling four times higher than SAURON, often revealing
previously undiscovered features. Around 75% (31/48) of the SAURON E/S0s
with central velocity dispersion ≳ 120 km s-1/ were
observed with OASIS, covering well the original SAURON representative
sample. We present here an overview of this follow-up survey, and some
preliminary results on individual objects, including a previously
unreported counter-rotating core in NGC 4382; the decoupled stellar and
gas velocity fields of NGC 2768; and the strong age gradient towards the
centre of NGC 3489.
