Bayesian correction of $H (z)$ data uncertainties

J. F. Jesus, T. M. Gregório, F. Andrade-Oliveira +2

We compile 41 $H (z)$ data from literature and use them to constrain O $Λ$ CDM and flat $Λ$ CDM parameters. We show that the available $H (z)$ suffers from uncertainties overestimation…

The Splashback Feature around DES Galaxy Clusters: Galaxy Density and Weak Lensing Profiles

C. Chang, E. Baxter, B. Jain +82

Splashback refers to the process of matter that is accreting onto a dark matter halo reaching its first orbital apocenter and turning around in its orbit. The cluster-centric radiu…

Density split statistics: joint model of counts and lensing in cells

O. Friedrich, D. Gruen, J. DeRose +71

We present density split statistics, a framework that studies lensing and counts-in-cells as a function of foreground galaxy density, thereby providing a large-scale measurement of…

Density split statistics: Cosmological constraints from counts and lensing in cells in DES Y1 and SDSS data

D. Gruen, O. Friedrich, E. Krause +93

We derive cosmological constraints from the probability distribution function (PDF) of evolved large-scale matter density fluctuations. We do this by splitting lines of sight by de…
