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…
Relativistic matter bispectrum of cosmic structures on the light cone
Thomas Montandon, Julian Adamek, Oliver Hahn +4
Upcoming surveys of cosmic structures will probe scales close to the cosmological horizon, which opens up new opportunities for testing the cosmological concordance model to high a…
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…
Structure formation in an anisotropic universe: Eulerian perturbation theory
Juan P. Beltrán Almeida, Josué Motoa-Manzano, Jorge Noreña +2
We present an effective Eulerian description, in the non-relativistic regime, of the growth of cosmological perturbations around a homogeneous but anisotropic Bianchi I spacetime b…
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…
