Euclid preparation. XLI. Galaxy power spectrum modelling in real space
Euclid Collaboration, A. Pezzotta, C. Moretti +246
We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…
The halo 3-point correlation function: a methodological analysis
A. Veropalumbo, A. Binetti, E. Branchini +5
We measure the 3PCF of 300 halo catalogs from the Minerva simulations covering a total volume of . Each 3PCF measurement includes all possible triangul…
The Halo Bispectrum Multipoles in Redshift Space
Federico Rizzo, Chiara Moretti, Kevin Pardede +5
We present the analysis of the halo bispectrum in redshift-space in terms of its multipoles, monopole, quadrupole and hexadecapole, measured from a large set of simulations. We fit…
Cosmological parameters from the likelihood analysis of the galaxy power spectrum and bispectrum in real space
Andrea Oddo, Federico Rizzo, Emiliano Sefusatti +2
We present a joint likelihood analysis of the halo power spectrum and bispectrum in real space. We take advantage of a large set of numerical simulations and of an even larger set…
The reach of next-to-leading-order perturbation theory for the matter bispectrum
Davit Alkhanishvili, Cristiano Porciani, Emiliano Sefusatti +4
We provide a comparison between the matter bispectrum derived with different flavours of perturbation theory at next-to-leading order and measurements from an unprecedentedly large…
Towards cosmological constraints from the compressed modal bispectrum: a robust comparison of real-space bispectrum estimators
Joyce Byun, Andrea Oddo, Cristiano Porciani +1
Higher-order clustering statistics, like the galaxy bispectrum, can add complementary cosmological information to what is accessible with two-point statistics, like the power spect…
Toward a robust inference method for the galaxy bispectrum: likelihood function and model selection
Andrea Oddo, Emiliano Sefusatti, Cristiano Porciani +2
The forthcoming generation of galaxy redshift surveys will sample the large-scale structure of the Universe over unprecedented volumes with high-density tracers. This advancement w…
