    The active centaur 2020 MK<SUB>4</SUB>
    Context. Centaurs go around the Sun between the orbits of Jupiter and Neptune. Only a fraction of the known centaurs have been found to display comet-like...

    The activity of comet C/2007 D1 (LINEAR) at 9.7 AU from the Sun
    Aims: We report on the unusual distant activity of the dynamically new comet C/2007 D1 (LINEAR), observed at rh = 9.7 AU post-perihelion. This comet is...

    The activity of comet C/2007 D1 (LINEAR) at 9.7 AU from the Sun (Corrigendum)
    Based on observations collected at the Italian Telescopio Nazionale Galileo (TNG), operated on the island of La Palma by the Centro Galileo Galilei of the INAF...

    The age of extremely red and massive galaxies at very high redshift
    Aims: We present a determination of the intrinsic colors and ages of galaxies at very high redshift, in particular old galaxies (OGs) within extremely red...

    The age-mass relation for chromospherically active binaries. II. Lithium depletion in dwarf components.
    We present an extensive study of lithium abundances in dwarf components of chromospherically active binary stars (CABS). Since most of these binaries have known...

    The age-mass relation for chromospherically active binaries. III. Lithium depletion in giant components
    We present a study of the lithium abundances of a sample of evolved components of Chromospherically Active Binary Systems. We show that a significant part of...

    The AGN contribution to mid-infrared surveys. X-ray counterparts of the mid-IR sources in the Lockman Hole and HDF-N
    We provide constraints on the AGN contribution to the mid-IR extragalactic background light from a correlation analysis of deep X-ray and mid-IR observations in...

    The ALHAMBRA survey: 2D analysis of the stellar populations in massive early-type galaxies at z < 0.3
    We present a technique that permits the analysis of stellar population gradients in a relatively low-cost way compared to integral field unit (IFU) surveys. We...

    The ALHAMBRA survey: accurate merger fractions derived by PDF analysis of photometrically close pairs
    Aims: Our goal is to develop and test a novel methodology to compute accurate close-pair fractions with photometric redshifts. Methods: We improved the...
