    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: a Large Area Multimedium-Band Optical and Near-Infrared Photometric Survey
    Here we describe the first results of the Advanced Large Homogeneous Area Medium-Band Redshift Astronomical (ALHAMBRA) survey, which provides cosmic tomography...

    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: 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: evolution of galaxy clustering since z ˜ 1
    We study the clustering of galaxies as function of luminosity and redshift in the range 0.35 z 1.25 using data from the Advanced Large Homogeneous Area Medium...
