Joint analysis of anisotropic power spectrum, bispectrum and trispectrum: application to N-body simulations

Davide Gualdi, Hector Gil-Marin, Licia Verde

We perform for the first time a joint analysis of the monopole and quadrupoles for power spectrum, bispectrum and integrated trispectrum (i-trispectrum) from the redshift space mat…

GEOMAX: beyond linear compression for 3pt galaxy clustering statistics

Davide Gualdi, Héctor Gil-Marín, Marc Manera +2

We present the GEOMAX algorithm and its Python implementation for a two-step compression of bispectrum measurements. The first step groups bispectra by the geometric properties of…

Beyond two-point statistics: using the minimum spanning tree as a tool for cosmology

Krishna Naidoo, Lorne Whiteway, Elena Massara +5

Cosmological studies of large-scale structure have relied on two-point statistics, not fully exploiting the rich structure of the cosmic web. In this paper we show how to capture s…

Geometrical compression: a new method to enhance the BOSS galaxy bispectrum monopole constraints

Davide Gualdi, Héctor Gil-Marín, Marc Manera +2

We present a novel method to compress galaxy clustering three-point statistics and apply it to redshift space galaxy bispectrum monopole measurements from BOSS DR12 CMASS data cons…

Enhancing BOSS bispectrum cosmological constraints with maximal compression

Davide Gualdi, Héctor Gil-Marín, Robert L. Schuhmann +3

We apply two compression methods to the galaxy power spectrum monopole/quadrupole and bispectrum monopole measurements from the BOSS DR12 CMASS sample. Both methods reduce the dime…

Maximal compression of the redshift space galaxy power spectrum and bispectrum

Davide Gualdi, Marc Manera, Benjamin Joachimi +1

We explore two methods of compressing the redshift space galaxy power spectrum and bispectrum with respect to a chosen set of cosmological parameters. Both methods involve reducing…
