Impact of Relativistic Effects on the Primordial Non-Gaussianity Signature in the Large-Scale Clustering of Quasars
Mike Shengbo Wang, Florian Beutler, David Bacon
Relativistic effects in clustering observations have been shown to introduce scale-dependent corrections to the galaxy over-density field on large scales, which may hamper the dete…

Cosmological Inference from Galaxy-Clustering Power Spectrum: Gaussianization and Covariance Decomposition
Mike Shengbo Wang, Will J. Percival, Santiago Avila +2
Likelihood fitting to two-point clustering statistics made from galaxy surveys usually assumes a multivariate normal distribution for the measurements, with justification based on…

A Unified Analysis of Four Cosmic Shear Surveys
Chihway Chang, Michael Wang, Scott Dodelson +13
In the past few years, several independent collaborations have presented cosmological constraints from tomographic cosmic shear analyses. These analyses differ in many aspects: the…
