    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...

    The ALHAMBRA survey: An empirical estimation of the cosmic variance for merger fraction studies based on close pairs
    Aims: Our goal is to estimate empirically the cosmic variance that affects merger fraction studies based on close pairs for the first time. Methods: We compute...

    The ALHAMBRA survey: B-band luminosity function of quiescent and star-forming galaxies at 0.2 ≤ z < 1 by PDF analysis
    Aims: Our goal is to study the evolution of the B-band luminosity function (LF) since z 1 using ALHAMBRA data. Methods: We used the photometric redshift and the...

    The ALHAMBRA survey: Discovery of a faint QSO at z = 5.41
    Aims: We aim to illustrate the potentiality of the Advanced Large, Homogeneous Area, Medium-Band Redshift Astronomical (ALHAMBRA) survey to investigate the high...

    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...
