Two is better than one: joint statistics of density and velocity in concentric spheres as a cosmological probe
Cora Uhlemann, Sandrine Codis, Oliver Hahn +2
The analytical formalism to obtain the probability distribution functions (PDFs) of spherically-averaged cosmic densities and velocity divergences in the mildly non-linear regime i…
Beyond Kaiser bias: mildly non-linear two-point statistics of densities in distant spheres
C. Uhlemann, S. Codis, J. Kim +5
Simple parameter-free analytic bias functions for the two-point correlation of densities in spheres at large separation are presented. These bias functions generalize the so-called…
The large-scale correlations of multi-cell densities and profiles, implications for cosmic variance estimates
Sandrine Codis, Francis Bernardeau, Christophe Pichon
In order to quantify the error budget in the measured probability distribution functions of cell densities, the two-point statistics of cosmic densities in concentric spheres is in…
