    Non-Gaussianity from Large-Scale Structure Surveys by Licia Verde

    Published 2010-01-01
    “…With the advent of galaxy surveys which provide large samples of galaxies or galaxy clusters over a volume comparable to the horizon size (SDSS-III, HETDEX, Euclid, JDEM, LSST, Pan-STARRS, CIP, etc.) or mass-selected large cluster samples over a large fraction of the extra-galactic sky (Planck, SPT, ACT, CMBPol, B-Pol), it is timely to investigate what constraints these surveys can impose on primordial non-Gaussianity. …”

    Clustering of X-Ray-Selected AGN by N. Cappelluti, V. Allevato, A. Finoguenov

    Published 2012-01-01
    “…In particular, one of the key results is that X-ray AGNs are hosted by dark matter halos of mass similar to that of galaxy groups. This result, together with model predictions, has lead to the hypothesis that galaxy mergers may constitute the main AGN-triggering mechanism. …”

    High-energy Neutrino Source Cross-correlations with Nearest-neighbor Distributions by Zhuoyang Zhou, Jessi Cisewski-Kehe, Ke Fang, Arka Banerjee

    Published 2025-01-01
    “…We conduct a statistical power analysis of an associated likelihood ratio test with estimations of its sensitivity and discovery potential with synthetic neutrino data samples and a WISE–2MASS galaxy sample. We apply the method to IceCube’s public ten-year point-source data and find no statistically significant evidence for spatial cross-correlations with the selected galaxy sample. …”
