Constructing Regularized Cosmic Propagators
Francis Bernardeau, Martin Crocce, Roman Scoccimarro
We present a new scheme for the general computation of cosmic propagators that allow to interpolate between standard perturbative results at low-k and their expected large-k resumm…
The Halo Bispectrum in N-body Simulations with non-Gaussian Initial Conditions
Emiliano Sefusatti, Martin Crocce, Vincent Desjacques
We present measurements of the bispectrum of dark matter halos in numerical simulations with non-Gaussian initial conditions of the local type. We show, in the first place, that th…
Cross-Correlation of spectroscopic and photometric galaxy surveys: cosmology from lensing and redshift distortions
E. Gaztanaga, M. Eriksen, M. Crocce +5
Cosmological galaxy surveys aim at mapping the largest volumes to test models with techniques such as cluster abundance, cosmic shear correlations or baryon acoustic oscillations (…
Clustering of Photometric Luminous Red Galaxies II: Cosmological Implications from the Baryon Acoustic Scale
A. Carnero, E. Sanchez, M. Crocce +2
A new determination of the sound horizon scale in angular coordinates is presented. It makes use of ~ 0.6 x 10^6 Luminous Red Galaxies, selected from the Sloan Digital Sky Survey i…
Clustering of photometric luminous red galaxies I : Growth of Structure and Baryon Acoustic Feature
Martin Crocce, Enrique Gaztanaga, Anna Cabre +2
The possibility of measuring redshift space (RSD) distortions using photometric data have been recently highlighted. This effect complements and significantly alters the detectabil…
Measuring Redshift-Space Distortions using Photometric Surveys
Ashley J Ross, Will J Percival, Martin Crocce +2
We outline how redshift-space distortions (RSD) can be measured from the angular correlation function w(θ), of galaxies selected from photometric surveys. The natural degeneracy be…
