Cosmological Model Parameter Dependence of the Matter Power Spectrum Covariance from the DEUS-PUR Simulations
Linda Blot, Pier-Stefano Corasaniti, Yann Rasera +1
Future galaxy surveys will provide accurate measurements of the matter power spectrum across an unprecedented range of scales and redshifts. The analysis of these data will require…
Comparing approximate methods for mock catalogues and covariance matrices III: Bispectrum
Manuel Colavincenzo, Emiliano Sefusatti, Pierluigi Monaco +19
We compare the measurements of the bispectrum and the estimate of its covariance obtained from a set of different methods for the efficient generation of approximate dark matter ha…
Comparing approximate methods for mock catalogues and covariance matrices II: Power spectrum multipoles
Linda Blot, Martin Crocce, Emiliano Sefusatti +19
We study the accuracy of several approximate methods for gravitational dynamics in terms of halo power spectrum multipoles and their estimated covariance matrix. We propagate the d…
Comparing approximate methods for mock catalogues and covariance matrices I: correlation function
Martha Lippich, Ariel G. Sánchez, Manuel Colavincenzo +19
This paper is the first in a set that analyses the covariance matrices of clustering statistics obtained from several approximate methods for gravitational structure formation. We…
The modified gravity lightcone simulation project I: Statistics of matter and halo distributions
Christian Arnold, Pablo Fosalba, Volker Springel +2
We introduce a set of four very high resolution cosmological simulations for exploring -gravity, with particles in and $1536\,h^{-1}\textrm…
