    The ALHAMBRA survey: Estimation of the clustering signal encoded in the cosmic variance
    Aims: The relative cosmic variance (σv) is a fundamental source of uncertainty in pencil-beam surveys and, as a particular case of count-in-cell statistics, can...

    The ALHAMBRA survey: tight dependence of the optical mass-to-light ratio on galaxy colour up to z = 1.5
    Aims: Our goal is to characterise the dependence of the optical mass-to-light ratio on galaxy colour up to z = 1.5, expanding the redshift range explored in...

    The alpha -element abundances in the most oxygen-poor planetary nebula PNG 135.9+55.9
    We present extensive new spectroscopy and imaging of PNG 135.9+55.9. We use these data as constraints to photoionization models to derive limits on the oxygen...

    The ALPINE-ALMA [CII] Survey: Unveiling the baryon evolution in the interstellar medium of z ∼ 5 star-forming galaxies
    Context. Recent observations suggest a significant and rapid buildup of dust in galaxies at high redshift (z > 4); this presents new challenges to our...

    The AMIGA sample of isolated galaxies. XIV. Disc breaks and interactions through ultra-deep optical imaging
    Context. In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are...

    The Araucaria Project: VLT-spectroscopy of blue massive stars in NGC 55
    Aims: This is the first paper of a series devoted to studying the population of blue massive stars in NGC 55, a galaxy of the Sculptor group at a distance of...
