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…
Moving around the cosmological parameter space: a nonlinear power spectrum reconstruction based on high-resolution cosmic responses
Takahiro Nishimichi, Francis Bernardeau, Atsushi Taruya
We present numerical measurements of the power spectrum response function of the gravitational growth of cosmic structures, defined as the functional derivative of the nonlinear sp…
Large deviations theory approach to cosmic shear calculations: the one-point aperture mass
Paulo Reimberg, Francis Bernardeau
This paper presents a general formalism that allows the derivation of the cumulant generating function and one-point Probability Distribution Function (PDF) of the aperture mass ($…
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…
