    Faint C and O recombination lines in H II regions and large telescopes: The case of S311
    We present preliminary results on the analysis of very deep echelle UVES (8m VLT) spectra of the Galactic H II region S311 (NGC 2467) located outside the Solar...

    Field O stars: formed in situ or as runaways?
    A significant fraction of massive stars in the Milky Way and other galaxies are located far from star clusters and star-forming regions. It is known that some...

    First steps of the GTC photometric calibration plan
    Large telescopes require a very precise calibration in order to maximize its scientific output. Current catalogues of standard stars are generally too bright...

    Formation of Slowly Rotating Elliptical Galaxies in Major Mergers. A Resolution Study
    We study resolution effects in numerical simulations of gas-rich (20% of the total baryonic mass) major mergers, and show that the formation of slowly-rotating...

    From blue cloud to red sequence: evidence of morphological transition prior to star formation quenching
    We present a study of a sample of 254 clusters from the SDSS-DR7 Yang Catalogue and an auxiliary sample of field galaxies to perform a detailed investigation on...

    From kpcs to the central parsec of NGC 1097: feeding star formation and a black hole at the same time
    A panchromatic view of the star-forming ring and feeding process in the central kpc of the galaxy NGC 1097 is presented. The assembled IR to UV images at ˜10 pc...

    From the blue cloud to the red sequence (and over the green valley): investigating the evolution of galaxies over cosmological timescales
    In the local universe, galaxies fall into one of two populations: a star-forming blue cloud and a red sequence lacking star formation. At redshift z ~ 1.5...

    Fueling and Morphology of Central Starbursts
    Of the mechanisms proposed to bring gaseous fuel into the central starburst regions of a galaxy, non-axisymmetries in the gravitational potential set up by...
