Towards counts-in-cells statistics for galaxy surveys — •Cora Uhlemann — Institute for Theoretical Physics, Utrecht University

Recently, we developed an analytical formalism to predict the one-point probability distribution of the dark matter density in spheres from the Gaussian initial conditions using the spherical collapse model. Here, we present how this theory can be extended to biased tracers such as dark matter halos and galaxies and hence used to predict counts-in-cells statistics for galaxy surveys.
