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…
Encircling the dark: constraining dark energy via cosmic density in spheres
S. Codis, C. Pichon, F. Bernardeau +2
The recently published analytic probability density function for the mildly non-linear cosmic density field within spherical cells is used to build a simple but accurate maximum li…
Spin alignments within the cosmic web: a theory of constrained tidal torques near filaments
Sandrine Codis, Christophe Pichon, Dmitry Pogosyan
The geometry of the cosmic web drives in part the spin acquisition of galaxies. This can be explained in a Lagrangian framework, by identifying the specific long-wavelength correla…
