    Spider. IV. Optical and Near-infrared Color Gradients in Early-type Galaxies: New Insight into Correlations with Galaxy Properties
    We present an analysis of stellar population gradients in 4546 early-type galaxies (ETGs) with photometry in grizYHJK along with optical spectroscopy. ETGs were...

    Spin alignment of dark matter haloes in the shells of the largest voids
    Using the high-resolution cosmological N-body simulation MareNostrum universe we study the orientation of shape and angular momentum of galaxy-size dark matter...

    Spin-up of low-mass classical bulges in barred galaxies
    Secular evolution is one of the key routes through which galaxies evolve along the Hubble sequence. Not only does the disc undergo morphological and kinematic...

    Spin-up of massive classical bulges during secular evolution
    Context. Classical bulges in spiral galaxies are known to rotate, but the origin of this observed rotational motion is not well understood. It has been shown...

    Spiral galaxies in the SAURON survey
    We discuss some recent integral field spectroscopy using the SAURON instrument of a sample consisting of 24 early-type spirals, part of the SAURON Survey, and...

    Spiral Inflow Feeding the Nuclear Starburst in M83, Observed in Hα Emission with the GHαFaS Fabry-Perot Interferometer
    We present observations of the nearby barred starburst galaxy M83 (NGC 5236), with the new Fabry-Perot interferometer GHαFaS mounted on the 4.2 m William...

    Spiral structure in barred galaxies. Observational constraints to spiral arm formation mechanisms
    A method, which we have developed for determining corotation radii, has allowed us to map in detail the radial resonant structures of barred spiral galaxies...

    SPIRE (f250um>17.4mJy) GOODS-N galaxies (Symeonidis+, 2011)
    The IR data come from the Herschel/SPIRE Science Demonstration Phase (SDP) observations of the Great Observatories Origins Deep Survey (GOODS)-North, taken as...

    SPIRE imaging of M 82: Cool dust in the wind and tidal streams
    M 82 is a unique representative of a whole class of galaxies, starbursts with superwinds, in the Very Nearby Galaxy Survey with Herschel. In addition, its...
