Non-Gaussianity as a Probe of the Physics of the Primordial Universe and the Astrophysics of the Low Redshift Universe
E. Komatsu, N. Afshordi, N. Bartolo +58
A new and powerful probe of the origin and evolution of structures in the Universe has emerged and been actively developed over the last decade. In the coming decade, non-Gaussiani…
Generation of Vorticity and Velocity Dispersion by Orbit Crossing
Sebastian Pueblas, Roman Scoccimarro
We study the generation of vorticity and velocity dispersion by orbit crossing using cosmological numerical simulations, and calculate the backreaction of these effects on the evol…
Multi-Point Propagators in Cosmological Gravitational Instability
Francis Bernardeau, Martin Crocce, Roman Scoccimarro
We introduce the concept of multi-point propagators between linear cosmic fields and their nonlinear counterparts in the context of cosmological perturbation theory. Such functions…
An analytic model for the bispectrum of galaxies in redshift space
Robert E. Smith, Ravi K. Sheth, Roman Scoccimarro
We develop an analytic theory for the redshift space bispectrum of dark matter, haloes and galaxies. This is done within the context of the halo model of structure formation, as th…
Nonlinear Evolution of Baryon Acoustic Oscillations
M. Crocce, R. Scoccimarro
We study the nonlinear evolution of the baryon acoustic oscillations (BAO) in the dark matter power spectrum and correlation function using renormalized perturbation theory (RPT).…
The Clustering of Galaxy Groups: Dependence on Mass and Other Properties
Andreas A. Berlind, Eyal Kazin, Michael R. Blanton +3
We investigate the clustering of galaxy groups and clusters in the SDSS using the Berlind et al. (2006) group sample, which is designed to identify galaxy systems that each occupy…
