    Extreme emission-line galaxies out to z ~ 1 in zCOSMOS. I. Sample and characterization of global properties
    Context. The study of large and representative samples of low-metallicity star-forming galaxies at different cosmic epochs is of great interest to the detailed...

    Extreme star formation events in quasar hosts over 0.5 < z < 4
    We explore the relationship between active galactic nuclei (AGN) and star formation in a sample of 513 optically luminous type 1 quasars up to redshifts of ˜4...

    Extremely metal-poor stars in classical dwarf spheroidal galaxies: Fornax, Sculptor, and Sextans
    We present the results of a dedicated search for extremely metal-poor stars in the Fornax, Sculptor, and Sextans dSphs. Five stars were selected from two...

    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...
