    (1) Stellar kinematics in double-barred galaxies: the sigma-hollows (2) A colorful view on the outskirt of spiral galaxies: clues on disk-formation scenarios

    (1) We present SAURON integral-field stellar velocity and velocity dispersion maps for four double-barred early-type galaxies: NGC2859, NGC3941,NGC4725 and...

    A step further in the Stellar Populations analysis of nearby galaxies: Surface Brightness Fluctuations

    Using deep photometry SBFs have been traditionally used to determine galaxy distances. We have recentlycomputed SBF spectra of stellar populations at moderately...

    An optical/NIR survey of globular clusters in early-type galaxies

    The colour distribution of globular cluster (GC) systems in the majority of galaxies is bi/multimodal in optical colours. It is widely accepted that multiple...

    Bar characterization from S4G imaging: Gaining insight into the secular evolution of disc galaxies

    The ΛCDM model predicts that galaxies originate in dark matter haloes, undergoing in their early age a process of continuous merges with other galaxies that...

    Calar Alto Legacy Integral Field Area survey

    CALIFA is the largest IFS survey ever performed up to date. Recently started, it will observe ~600 galaxies in the Local Universe with PPAK at the 3.5m of the...

    Dark matter in early-type galaxies: a SAURON view

    From galaxy formation theory we expect galaxies to be embedded in massive dark matter haloes. For spiral and dwarf galaxies this has indeed been observationally...

    Dynamics of galaxies and globular clusters unraveled with two-dimensional kinematics

    Two-dimensional stellar kinematics obtained with the integral-field spectrograph SAURON allow the classification of early-type galaxies into 'slow' and 'fast'...

    Early-type galaxies: application of a new spectrophotometric population synthesis model.

    The authors have applied a new spectrophotometric stellar population synthesis model, designed to study early-type galaxies (Vazdekis, Casuso et al. 1995), to...

    Globular cluster systems and the origin of early-type dwarfs in Virgo

    Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or recent end-products of the...
