Caught in the rhythm II: Competitive alignments of satellites with their inner halo and central galaxy
Charlotte Welker, Chris Power, Christophe Pichon +3
The anisotropic distribution of satellites around the central galaxy of their host halo is well-documented. However the relative impact of baryons and dark matter in shaping this d…
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…
