    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...

    Stellar Populations of Globular Clusters in the Elliptical Galaxy NGC 1407
    We present high-quality Keck spectroscopic data for a sample of 20 globular clusters (GCs) in the massive E0 galaxy NGC 1407. A subset of 20 line-strength...

    Stellar populations of massive elliptical galaxies in very rich clusters
    We present a detailed stellar population analysis of 27 massive elliptical galaxies within four very rich clusters at redshift z ~ 0.2: A115, A655, A963 and...

    Stellar splashback: the edge of the intracluster light
    We examine the outskirts of galaxy clusters in the C-EAGLE simulations to quantify the 'edges' of the stellar and dark matter distribution. The radius of the...

    Stellar Tidal Streams in Spiral Galaxies of the Local Volume: A Pilot Survey with Modest Aperture Telescopes
    Within the hierarchical framework for galaxy formation, minor merging and tidal interactions are expected to shape all large galaxies to the present day. As a...
