MEDUSA: Minkowski functionals estimated from Delaunay tessellations of the three-dimensional large-scale structure
Martha Lippich, Ariel G. Sánchez
Minkowski functionals (MFs) are a set of statistics that characterise the geometry and topology of the cosmic density field and contain complementary information to the standard tw…
One simulation to have them all: performance of the Bias Assignment Method against N-body simulations
Andrés Balaguera-Antolínez, Francisco-Shu Kitaura, Marcos Pellejero-Ibáñez +6
In this paper we demonstrate that the information encoded in \emph{one} single (sufficiently large) -body simulation can be used to reproduce arbitrary numbers of halo catalogue…
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…
