Cosmological inference including massive neutrinos from the matter power spectrum: biases induced by uncertainties in the covariance matrix
S. Gouyou Beauchamps, P. Baratta, S. Escoffier +4
Data analysis from upcoming large galaxy redshift surveys, such as Euclid and DESI will significantly improve constraints on cosmological parameters. To optimally extract the infor…
COVMOS: a new Monte Carlo approach for galaxy clustering analysis
Philippe Baratta, Julien Bel, Sylvain Gouyou Beauchamps +1
We validate the COVMOS method introduced in Baratta et al. (2019) allowing for the fast simulation of catalogues of different cosmological field tracers (e.g. dark matter particles…
The multipole expansion of the local expansion rate
Basheer Kalbouneh, Christian Marinoni, Julien Bel
We design a new observable, the expansion rate fluctuation , to characterize deviations from the linear relation between redshift and distance in the local universe. We also sho…
DEMNUni: comparing nonlinear power spectra prescriptions in the presence of massive neutrinos and dynamical dark energy
G. Parimbelli, C. Carbone, J. Bel +4
We provide an accurate comparison, against large cosmological -body simulations, of different prescriptions for modelling nonlinear matter power spectra in the presence of massi…
Constraining spatial curvature with large-scale structure
Julien Bel, Julien Larena, Roy Maartens +2
We analyse the clustering of matter on large scales in an extension of the concordance model that allows for spatial curvature. We develop a consistent approach to curvature and wi…
The VIMOS Public Extragalactic Redshift Survey (VIPERS) -- Environment-size relation of massive passive galaxies at 0.5 < z < 0.8
A. Gargiulo, O. Cucciati, B. Garilli +36
We use the statistics of the VIPERS survey to investigate the relation between the surface mean stellar mass density Sigma=Mstar/(2*pi*Re^2) of massive passive galaxies (MPGs, Msta…
