Bounds on WIMP dark matter from galaxy clusters at low redshift
Xiuhui Tan, Manuel Colavincenzo
The study of the cross-correlation angular power spectrum between gravitational tracers and electromagnetic signals can be a powerful tool to constrain Dark Matter (DM) microscopic…
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…
