Statistical exploration of halo anisotropic clustering and intrinsic alignments with the mass-Peak Patch algorithm

no code implementations5 Jan 2021 Bruno Regaldo-Saint Blancard, Sandrine Codis, J. Richard Bond, George Stein

The anisotropy or triaxiality of massive dark matter haloes largely defines the structure of the cosmic web, in particular the filaments that join the haloes together.

Non-perturbative halo clustering from cosmological density peaks

no code implementations28 Dec 2020 Tobias Baldauf, Sandrine Codis, Vincent Desjacques, Christophe Pichon

Our predictions are in good agreement with the Lagrangian clustering of dark matter proto-haloes reconstructed from N-body simulations.

no code implementations14 Dec 2020 Aoife Boyle, Cora Uhlemann, Oliver Friedrich, Alexandre Barthelemy, Sandrine Codis, Francis Bernardeau, Carlo Giocoli, Marco Baldi

Pinning down the total neutrino mass and the dark energy equation of state is a key aim for upcoming galaxy surveys.

Probability distribution function of the aperture mass field with large deviation theory

no code implementations7 Dec 2020 Alexandre Barthelemy, Sandrine Codis, Francis Bernardeau

Furthermore we show that, with the help of a nulling procedure based on the so-called BNT transform, it is possible to build observables that depend only on a finite range of redshifts making them also independent from the small-scale modes.
