    Stellar Populations in the Outskirts of the Small Magellanic Cloud: No Outer Edge Yet
    We report the detection of intermediate-age and old stars belonging to the SMC at 6.5 kpc from the SMC center in the southern direction. We show, from the...

    Stellar populations of bulges in 14 cluster disc galaxies
    Photometry and long-slit spectroscopy are presented for 14 S0 and spiral galaxies of the Fornax, Eridanus and Pegasus cluster, and NGC 7582 group. The...

    Stellar populations of bulges in galaxies with a low surface-brightness disc
    The radial profiles of the Hβ, Mg, and Fe line-strength indices are presented for a sample of eight spiral galaxies with a low surface-brightness stellar disc...

    Stellar populations of disc galaxies: from the center of the bulge to the edge of the disc
    We present extensive photometric and spectroscopic study to give a new insight in the bulge stellar population. Super-solar α/Fe and its constant value along...

    Stellar Populations of Elliptical Galaxies in Virgo Cluster. I. The Data and Stellar Population Analysis
    We have determined spectroscopic ages of elliptical galaxies in the Virgo Cluster using spectra of very high signal-to-noise ratio (S/N>100 Å-1). We observed...

    Stellar populations of galaxies in the ALHAMBRA survey up to z ~ 1. I. MUFFIT: A multi-filter fitting code for stellar population diagnostics
    Aims: We present MUFFIT, a new generic code optimized to retrieve the main stellar population parameters of galaxies in photometric multi-filter surveys, and...

    Stellar populations of galaxies in the ALHAMBRA survey up to z ̃ 1. II. Stellar content of quiescent galaxies within the dust-corrected stellar mass-colour and the UVJ colour-colour diagrams
    Aims: Our aim is to determine the distribution of stellar population parameters (extinction, age, metallicity, and star formation rates) of quiescent galaxies...

    Stellar populations of galaxies in the ALHAMBRA survey up to z ̃ 1. III. The stellar content of the quiescent galaxy population during the last 8 Gyr
    Aims: We aim at constraining the stellar population properties of quiescent galaxies. These properties reveal how these galaxies evolved and assembled since z ̃...

    Stellar populations of galaxies in the ALHAMBRA survey up to z ̃ 1. IV. Properties of quiescent galaxies on the stellar mass-size plane
    Aims: We perform a comprehensive study of the stellar population properties (formation epoch, age, metallicity, and extinction) of quiescent galaxies as a...
