Modeling scale-dependent bias on the baryonic acoustic scale with the statistics of peaks of Gaussian random fields
Vincent Desjacques, Martin Crocce, Roman Scoccimarro +1
Models of galaxy and halo clustering commonly assume that the tracers can be treated as a continuous field locally biased with respect to the underlying mass distribution. In the p…
Multi-Point Propagators for Non-Gaussian Initial Conditions
Francis Bernardeau, Martin Crocce, Emiliano Sefusatti
We show here how Renormalized Perturbation Theory (RPT) calculations applied to the quasi-linear growth of the large-scale structure can be carried on in presence of primordial non…
Tracing The Sound Horizon Scale With Photometric Redshift Surveys
E. Sanchez, A. Carnero, J. Garcia-Bellido +6
We propose a new method for cosmological parameters extraction using the baryon acoustic oscillation scale as a standard ruler in deep galaxy surveys with photometric determination…
The Matter Bispectrum in N-body Simulations with non-Gaussian Initial Conditions
Emiliano Sefusatti, Martin Crocce, Vincent Desjacques
We present measurements of the dark matter bispectrum in N-body simulations with non-Gaussian initial conditions of the local kind for a large variety of triangular configurations…
Modeling the angular correlation function and its full covariance in Photometric Galaxy Surveys
Martin Crocce, Anna Cabre, Enrique Gaztañaga
Near future cosmology will see the advent of wide area photometric galaxy surveys, like the Dark Energy Survey (DES), that extent to high redshifts (z ~ 1 - 2) but with poor radial…
