    Quantifying the coherent outflows of galaxies around voids in the SDSS DR7
    We report the detection, with a high level of confidence, of coherent outflows around voids found in the seventh data release of the Sloan Digital Sky Survey...

    Quasars as a Tracer of Large-scale Structures in the Distant Universe
    We study the dependence of the number density and properties of quasars on the background galaxy density using the currently largest spectroscopic data sets of...
