Probing cosmology via the clustering of critical points

Junsup Shim, Christophe Pichon, Dmitri Pogosyan +5

Exclusion zones in the cross-correlations between critical points (peak-void, peak-wall, filament-wall, filament-void) of the density field define quasi-standard rulers that can be…

Estimating major merger rates and spin parameters ab initio via the clustering of critical events

Corentin Cadiou, Eric Pichon-Pharabod, Christophe Pichon +1

We build a model to predict from first principles the properties of major mergers. We predict these from the coalescence of peaks and saddle points in the vicinity of a given large…
