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…
Choose to smooth: Gaussian streaming with the truncated Zel'dovich approximation
Michael Kopp, Cora Uhlemann, Ixandra Achitouv
We calculate the dark matter halo correlation function in redshift space using the Gaussian streaming model (GSM). To determine the scale dependent functions entering the streaming…
Encircling the dark: constraining dark energy via cosmic density in spheres
S. Codis, C. Pichon, F. Bernardeau +2
The recently published analytic probability density function for the mildly non-linear cosmic density field within spherical cells is used to build a simple but accurate maximum li…
