Description
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.

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging & Astronomy
    Diffuse emission in the outskirts of galaxies, such as stellar tidal streams, galaxy stellar halos and intracluster light, provides important constraints on the structure and evolution of the Universe. However, such low surface brightness diffuse emission can be up to thousands of times dimmer (>29 AB mag/[square arcseconds]) than the sky

    A Systematic Search for and Characterization of White Dwarf Binaries Across the H-R Diagram
    White dwarfs (WDs) are the endpoint of evolution for 97% of stars. Most of these stars are in multiple systems, and a significant fraction of those are compact enough to exchange mass, altering the structures and subsequent evolution of both stars. The physical mechanisms that facilitate these mass exchanges include common envelope evolution, Roche

    The molecular gas perspective on the growth and death of H emitters in the Spiderweb protocluster at Alpha z=2.16
    Galaxy clusters at low redshift are dominated by massive quiescent galaxies hosting stellar populations 10 Gyrs old, indicating that they were formed in the early universe when clusters were still in the process of being assembled (i.e., protoclusters). The rapid growth of galaxies within protoclusters is driven by the efficient transformation of
