Improving constraints on the neutrino mass using sufficient statistics
M. Wolk, I. Szapudi, J. Bel +2
We use the "Dark Energy and Massive Neutrino Universe" (DEMNUni) simulations to compare the constraining power of "sufficient statistics" with the standard matter power spectrum on…
Unveiling the cosmological information beyond linear scales: forecasts for sufficient statistics
M. Wolk, J. Carron, I. Szapudi
Beyond the linear regime, Fourier modes of cosmological random fields become correlated, and the power spectrum of density fluctuations contains only a fraction of the available co…
The impact of super-survey modes on cosmological constraints from cosmic shear fields
Julien Carron, István Szapudi
Owing to the mass-sheet degeneracy, cosmic shear maps do not probe directly the Fourier modes of the underlying mass distribution on scales comparable to the survey size and larger…
On fast Generation of Cosmological Random Fields
Julien Carron, Melody Wolk, Istvan Szapudi
The statistical translation invariance of cosmological random fields is broken by a finite survey boundary, correlating the observable Fourier modes. Standard methods for generatin…
The information content of galaxy surveys
Julien Carron
A large fraction of this thesis is dedicated to the study of the information content of random fields with heavy tails, in particular the lognormal field, a model for the matter de…
On the assumption of Gaussianity for cosmological two-point statistics and parameter dependent covariance matrices
Julien Carron
In this brief paper we revisit the Fisher information content of cosmological power spectra or two-point functions of Gaussian fields in order to comment on the assumption of Gauss…
