Cylinders out of a top hat: counts-in-cells for projected densities
Cora Uhlemann, Christophe Pichon, Sandrine Codis +5
Large deviation statistics is implemented to predict the statistics of cosmic densities in cylinders applicable to photometric surveys. It yields few percent accurate analytical pr…
Hunting high and low: Disentangling primordial and late-time non-Gaussianity with cosmic densities in spheres
Cora Uhlemann, Enrico Pajer, Christophe Pichon +3
Non-Gaussianities of dynamical origin are disentangled from primordial ones using the formalism of large deviation statistics with spherical collapse dynamics. This is achieved by…
A question of separation: disentangling tracer bias and gravitational nonlinearity with counts-in-cells statistics
Cora Uhlemann, Martin Feix, Sandrine Codis +9
Starting from a very accurate model for density-in-cells statistics of dark matter based on large deviation theory, a bias model for the tracer density in spheres is formulated. It…
