    Line Strength Mapping of the Stellar Populations within Elliptical Galaxies
    Given the relevance of line strength gradients to study the formation and secular evolution of elliptical galaxies, we propose to measure deep line strength...

    Line-of-sight velocity distributions of elliptical galaxies from collisionless mergers
    We analyse the skewness of the line-of-sight velocity distributions in model elliptical galaxies built through collisionless galaxy mergers. We build the models...

    LINER-like Extended Nebulae in ULIRGs: Shocks Generated by Merger-Induced Flows
    In this work we studied the two-dimensional ionization structure of the circumnuclear and extranuclear regions in a sample of six low-z ultraluminous infrared...

    Linking star formation thresholds and truncations in the thin and thick disks of the low-mass galaxy UGC 7321
    Thin and thick disks are found in most spiral galaxies, yet their formation scenarios remain uncertain. Whether thick disks form through slow or fast, internal...

    Linking the internal properties of infant globular clusters to their formation environments
    We investigate the formation of infant globular cluster (GC) candidates in high-resolution cosmological simulations from the First Billion Years project. By...

    LITTLE THINGS in 3D: robust determination of the circular velocity of dwarf irregular galaxies
    Dwarf irregular galaxies (dIrrs) are the smallest stellar systems with extended H i discs. The study of the kinematics of such discs is a powerful tool to...

    Local anticorrelation between star formation rate and gas-phase metallicity in disc galaxies
    Using a representative sample of 14 star-forming dwarf galaxies in the local Universe, we show the existence of a spaxel-to-spaxel anticorrelation between the...

    Local Cosmology from Isolated Dwarfs: the derivation of star formation histories.
    The color-magnitude diagram (CMD) is the most powerful tool to derive quantitative star formation histories (SFHs) of complex stellar systems which host...

    Local Cosmology from Isolated Dwarfs: variable stars from the LCID project.
    During Cycle 14 a total of 113 HST orbits were secured to observe five isolated dwarf galaxies, namely Tucana, LGS3, LeoA, IC1613, and Cetus. The aim of the...
