    SPICA and the Chemical Evolution of Galaxies: The Rise of Metals and Dust
    The physical processes driving the chemical evolution of galaxies in the last 11Gyr cannot be understood without directly probing the dust-obscured phase of...

    SPIDER - I. Sample and galaxy parameters in the grizYJHK wavebands
    This is the first paper of a series presenting the Spheroids Panchromatic Investigation in Different Environmental Regions (SPIDER). The sample of spheroids...

    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...
