    SPIDER - II. The Fundamental Plane of early-type galaxies in grizYJHK
    We present a complete analysis of the Fundamental Plane (FP) of early-type galaxies (ETGs) in the nearby Universe (z 0.1). The sample, as defined in Paper I...

    SPIDER - III. Environmental dependence of the Fundamental Plane of early-type galaxies
    We analyse the Fundamental Plane (FP) relation of 39993 early-type galaxies (ETGs) in the optical (griz) and 5080 ETGs in the near-infrared (NIR; YJHK)...

    SPIDER - X. Environmental effects in central and satellite early-type galaxies through the stellar fossil record
    A detailed analysis of how environment affects the star formation history of early-type galaxies (ETGs) is undertaken via high signal-to-noise ratio stacked...

    SPIDER VIII - constraints on the stellar initial mass function of early-type galaxies from a variety of spectral features
    We perform a spectroscopic study to constrain the stellar initial mass function (IMF) by using a large sample of 24 781 early-type galaxies from the Sloan...

    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...
