Non-perturbative halo clustering from cosmological density peaks

no code implementations28 Dec 2020 Tobias Baldauf, Sandrine Codis, Vincent Desjacques, Christophe Pichon

Our predictions are in good agreement with the Lagrangian clustering of dark matter proto-haloes reconstructed from N-body simulations.

Information content in the redshift-space galaxy power spectrum and bispectrum

no code implementations8 Jul 2020 Nishant Agarwal, Vincent Desjacques, Donghui Jeong, Fabian Schmidt

We present a Fisher information study of the statistical impact of galaxy bias and selection effects on the estimation of key cosmological parameters from galaxy redshift surveys; in particular, the angular diameter distance, Hubble parameter, and linear growth rate at a given redshift, the cold dark matter density, and the tilt and running of the primordial power spectrum.
