    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...

    SPT clusters with DES and HST weak lensing. I. Cluster lensing and Bayesian population modeling of multiwavelength cluster datasets
    We present a Bayesian population modeling method to analyze the abundance of galaxy clusters identified by the South Pole Telescope (SPT) with a simultaneous...

    SPT clusters with DES and HST weak lensing. II. Cosmological constraints from the abundance of massive halos
    We present cosmological constraints from the abundance of galaxy clusters selected via the thermal Sunyaev-Zel'dovich (SZ) effect in South Pole Telescope (SPT)...

    Statistics of voids in the two-degree Field Galaxy Redshift Survey
    We present a statistical analysis of voids in the two-degree Field Galaxy Redshift Survey (2dFGRS). In order to detect the voids, we have developed two robust...

    Stellar content of extremely red quiescent galaxies at z > 2
    Context. A set of 20 extremely red galaxies at 2.5 ≤ zphot. ≤ 3.8 with photometric features of old passive-evolving galaxies without dust, with stellar masses...

    Stellar Disk Truncations: HI Density and Dynamics
    Using HI Nearby Galaxy Survey (THINGS) 21-cm observations of a sample of nearby (nearly face-on) galaxies we explore whether the stellar disk truncation...

    Stellar Populations and Kinematics of Red Galaxies at z > 2: Implications for the Formation of Massive Galaxies
    We recently identified a substantial population of galaxies at z>2 with comparatively red rest-frame optical colors. These distant red galaxies (DRGs) are...

    Stellar Populations and the Local Group Membership of the Dwarf Galaxy DDO 210
    We present deep BVI CCD photometry of the stars in the dwarf galaxy DDO 210. The color-magnitude diagrams of DDO 210 show a well-defined red giant branch (RGB)...
