Minkowski Tensors in Two Dimensions - Probing the Morphology and Isotropy of the Matter and Galaxy Density Fields
Stephen Appleby, Pravabati Chingangbam, Changbom Park +3
We apply the Minkowski Tensor statistics to two dimensional slices of the three dimensional density field. The Minkowski Tensors are a set of functions that are sensitive to direct…
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…
Cosmological constraints from the redshift dependence of the volume effect using the galaxy 2-point correlation function across the line-of-sight
Xiao-Dong Li, Changbom Park, Cristiano G. Sabiu +4
We develop a methodology to use the redshift dependence of the galaxy 2-point correlation function (2pCF) across the line-of-sight, , as a probe of cosmological parame…
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…
New fitting formula for cosmic non-linear density distribution
Jihye Shin, Juhan Kim, Christophe Pichon +2
We have measured the probability distribution function (PDF) of cosmic matter density field from a suite of N-body simulations. We propose the generalized normal distribution of ve…
Dark matter haloes in modified gravity and dark energy: interaction rate, small-, and large-scale alignment
Benjamin L'Huillier, Hans A. Winther, David F. Mota +2
We study the properties of dark matter haloes in a wide range of modified gravity models, namely, , DGP, and interacting dark energy models. We study the effects of modified…
