Descripción
Luminous Compact Blue Galaxies (LCBGs) are high surface brightness starburst galaxies bluer than a typical SBc and with typical luminosities ≈ L ⋆, which are undergoing a major burst of star formation. LCBGs are the closest counterparts to the large population of starburst galaxies observed at high redshift, including Lyman-break galaxies at z ≈ 2. However, because LCBGs are very rare in the nearby Universe, their properties are still largely unknown. We have selected a representative sample of LCBGs from the SDSS and UCM databases which, although small, provides an excellent reference for comparison with current and future surveys of similar starbursts at high-z. We are carrying out a 3D optical and radio spectroscopic study of this LCBG sample, including spatially resolved maps of kinematics, extinction, SFR and metallicity. This will allow us to characterize their star formation history and mass assembly, and the role of mergers and supernova galactic winds. Here we show our results of this comprehensive multiwavelength study for NGC 7673, a prototypical LCBG in the nearby Universe.

    A new era in galaxy edge characterisation with ultra-deep imaging
    For the first time, the LIGHTS survey is routinely imaging galaxies at a depth and spatial resolution comparable to what LSST will produce in 10 years (i.e. ~31 mag/arcsec^2). This opens up the possibility of probing the edge of galaxies with a precision that we have not been able to achieve in the past. While we have been limited to one

    Exploring the role of galaxy interactions in fuelling active galactic nuclei: mergers, star formation, and supermassive black hole accretion
    Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major mergers have the ability to drive gas inwards through the strong tidal torques involved, but observations trying to link mergers with AGN have found mixed results due to the difficulty of

    Star formation at the edge of galaxies
    At the edge of galaxies, in the lowest surface brightness regimes, lies the boundary where gas can collapse to form new stars. These regions remain largely unexplored due to the lack of very deep images that allow us to characterize the star-forming clumps at the edge of the discs. In this sense, we do not know whether stellar activity in these
