Bispectrum non-Gaussian Covariance in Redshift Space
Jacopo Salvalaggio, Lina Castiblanco, Jorge Noreña +2
We provide an analytical description of the galaxy bispectrum covariance and the power spectrum-bispectrum cross-covariance in redshift space that captures the dominant non-Gaussia…
A Model for the Squeezed Bispectrum in the Non-Linear Regime
Matteo Biagetti, Juan Calles, Lina Castiblanco +2
We present a model for the squeezed dark matter bispectrum, where the short modes are deep in the non-linear regime. We exploit the consistency relations for large-scale structures…
Fisher Forecasts for Primordial non-Gaussianity from Persistent Homology
Matteo Biagetti, Juan Calles, Lina Castiblanco +2
We study the information content of summary statistics built from the multi-scale topology of large-scale structures on primordial non-Gaussianity of the local and equilateral type…
The Covariance of Squeezed Bispectrum Configurations
Matteo Biagetti, Lina Castiblanco, Jorge Noreña +1
We measure the halo bispectrum covariance in a large set of N-body simulations and compare it with theoretical expectations. We find a large correlation among (even mildly) squeeze…
From matter to galaxies: General relativistic bias for the one-loop bispectrum
Juan Calles, Lina Castiblanco, Jorge Noreña +1
We write down the Lagrangian bias expansion in general relativity up to 4th order in terms of operators describing the curvature of an early-time hypersurface for comoving observer…
Relativistic cosmological large scale structures at one-loop
Lina Castiblanco, Radouane Gannouji, Jorge Noreña +1
The large scale structure bispectrum in the squeezed limit couples large with small scales. Since relativity is important at large scales and non-linear loop corrections are import…
