    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...

    Local and Global Gas Metallicity versus Stellar Age Relation in MaNGA Galaxies
    The search for new global scaling relations linking the physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially...

    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...

    Long slit spectroscopy of NGC 5506
    The galaxy NGC 5506 hosts an active nucleus, that presents characteristics that are intermediate between Sy1 and Sy2. We discuss long slit spectra of NGC 5506...

    Long slit spectroscopy of the nuclear zone of NGC 253
    A study has been undertaken of the physical conditions of the ionized gas within the starburst region of the galaxy NGC 253, using long slit spectroscopy at...

    Low-redshift quasars in the SDSS Stripe 82 - II. Associated companion galaxies and signature of star formation
    We present optical spectroscopy of the close companions of 22 low-redshift (z < 0.5) quasars (QSO) selected from a larger sample of QSO in the SDSS Stripe82...

    Ly α emitters as tracers of proto-cluster of galaxies at z ~ 2 - 4
    We propose to use the OSIRIS tunable filters to perform for the first time a systematic study of the environment of Radio Loud and Radio Quiet quasars in...

    Ly α emitters at z ~ 6 in the OTELO survey
    In this paper we discuss the detection of Ly α galaxies at 4.6 ≳ z ≳ 6.6 within the OTELO survey. We estimate the expected number of objects that will be found...

    Lyman break and ultraviolet-selected galaxies at z ˜ 1 - I. Stellar populations from the ALHAMBRA survey
    We take advantage of the exceptional photometric coverage provided by the combination of GALEX data in the ultraviolet (UV) and the ALHAMBRA survey in the...
