    The SAURON project - XI. Stellar populations from absorption-line strength maps of 24 early-type spirals
    We present absorption-line strength maps of a sample of 24 representative early-type spiral galaxies, mostly of type Sa, obtained as part of the SAURON...

    The SAURON project - XII. Kinematic substructures in early-type galaxies: evidence for discs in fast rotators
    We analysed two-dimensional maps of 48 early-type galaxies obtained with the SAURON and OASIS integral-field spectrographs using kinemetry, a generalization of...

    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...

    The SAURON Project - XIV. No escape from Vesc: a global and local parameter in early-type galaxy evolution
    We present the results of an investigation of the local escape velocity (Vesc) - line strength index relationship for 48 early-type galaxies from the SAURON...

    The SAURON project - XIX. Optical and near-infrared scaling relations of nearby elliptical, lenticular and Sa galaxies
    We present ground-based MDM Observatory V-band and Spitzer/InfraRed Array Camera 3.6-?m-band photometric observations of the 72 representative galaxies of the...

    The SAURON project - XV. Modes of star formation in early-type galaxies and the evolution of the red sequence
    We combine SAURON integral field data of a representative sample of local early-type, red sequence galaxies with Spitzer/Infrared Array Camera imaging in order...

    The SAURON project - XVI. On the sources of ionization for the gas in elliptical and lenticular galaxies
    Following our study on the incidence, morphology and kinematics of the ionized gas in early-type galaxies, we now address the question of what is powering the...

    The SAURON project - XVII. Stellar population analysis of the absorption line strength maps of 48 early-type galaxies
    We present a stellar population analysis of the absorption line strength maps for 48 early-type galaxies from the SAURON sample. Using the line strength index...

    The SAURON project - XVIII. The integrated UV-line-strength relations of early-type galaxies
    Using far-ultraviolet (FUV) and near-ultraviolet (NUV) photometry from guest investigator programmes on the Galaxy Evolution Explorer (GALEX) satellite, optical...
