    The outskirts of spiral galaxies: touching stellar halos at z˜0 and z˜1
    Taking advantage of ultra-deep imaging of SDSS Stripe82 and the Hubble Ultra Deep Field by HST, we explore the properties of stellar halos at two relevant...

    The PAU survey: classifying low-z SEDs using Machine Learning clustering
    We present an application of unsupervised Machine Learning clustering to the PAU survey of galaxy spectral energy distribution (SED) within the COSMOS field...

    The photometric properties of isolated early-type galaxies
    Isolated galaxies are important because they probe the lowest density regimes inhabited by galaxies. We define a sample of 36 nearby isolated early-type...

    The Properties of Satellite Galaxies in External Systems. II. Photometry and Colors
    In this second paper dedicated to the study of satellite galaxies we present broadband photometry in the B, V, R, and I filters of 49 satellite galaxies...

    The quantity of dark matter in early-type galaxies and its relation to the environment
    We study the behaviour of the dynamical and stellar mass inside the effective radius of early-type galaxies (ETGs) as a function of environment considering...

    The rapid fading of V1647 Orionis: the sudden end of a FUor-type eruption?
    The young eruptive star V1647 Ori started a rapid fading in October 2005 and now is only 1 mag above the pre-outburst level. Colour changes indicate that the...

    The Recent Star Formation History of NGC 5102
    We present Hubble Space Telescope photometry of young stars in NGC 5102, a nearby gas-rich post-starburst S0 galaxy with a bright young stellar nucleus. We use...

    The relationship between the Sérsic law profiles measured along the major and minor axes of elliptical galaxies
    In this paper we discuss the reason why the parameters of the Sérsic model best-fitting the major axis light profile of elliptical galaxies can differ...

    The SAURON project - XIII. SAURON-GALEX study of early-type galaxies: the ultraviolet colour-magnitude relations and Fundamental Planes
    We present Galaxy Evolution Explorer far-ultraviolet (FUV) and near-ultraviolet (NUV) imaging of 34 nearby early-type galaxies from the SAURON representative...
