Descripción
We are carrying out a project devoted to study the internal structure of
a representative sample of about 70 low-redshift LIRGs and ULIRGs using
several optical and near-IR IFS facilities. Here we present the main
characteristics of this project, and discuss recent results derived from
optical data obtained with the VIMOS / VLT instrument. In particular, we
comment on the 2D kinematics of the ionized and neutral gas for two
prototypical LIRGs. We also discuss the excitation conditions in the
extra-nuclear extended regions in LIRGs in terms of fundamental
properties of the systems, such as their luminosity and dynamical status
(isolated, pairs, or merger remnants). We found that the interaction
process itself, more than a super-wind caused by the star formation,
seems to be the main origin of the shocks in the extended extra-nuclear
regions of interacting and merging systems.
