    (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 new framework for investigating the evolution of Early Type Galaxies
    I present a detailed analysis of the scaling relations of ETGs and suggest a way to predict the evolution of the distributions of galaxies in these planes. This...

    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...

    Descubren la galaxia espiral barrada más lejana hasta la fecha
    Un equipo científico internacional, en el que participan investigadores del Instituto de Astrofísica de Canarias (IAC) y la Universidad de La Laguna (ULL)...

    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'...
