Galaxy Power Spectrum Multipoles Covariance in Perturbation Theory
Digvijay Wadekar, Roman Scoccimarro
We compute the covariance of the galaxy power spectrum multipoles in perturbation theory, including the effects of nonlinear evolution, nonlinear and nonlocal bias, radial redshift…
Constraining with the Bispectrum I: Breaking Parameter Degeneracies
ChangHoon Hahn, Francisco Villaescusa-Navarro, Emanuele Castorina +1
Massive neutrinos suppress the growth of structure below their free-streaming scale and leave an imprint on large-scale structure. Measuring this imprint allows us to constrain the…
The Quijote simulations
Francisco Villaescusa-Navarro, ChangHoon Hahn, Elena Massara +26
The Quijote simulations are a set of 44,100 full N-body simulations spanning more than 7,000 cosmological models in the hyperplane.…
A non-perturbative test of consistency relations and their violation
Angelo Esposito, Lam Hui, Roman Scoccimarro
In this paper, we verify the large scale structure consistency relations using N-body simulations, including modes in the highly non-linear regime. These relations (pointed out by…
