The energy shear of protohaloes
Marcello Musso, Giulia Despali, Ravi K. Sheth
As it collapses to form a halo, the shape of a protohalo patch is deformed by the initial shear field. This deformation is often modeled using the "deformation" tensor, constructed…
When do cosmic peaks, filaments or walls merge? A theory of critical events in a multi-scale landscape
Corentin Cadiou, Christophe Pichon, Sandrine Codis +5
The merging rate of cosmic structures is computed, relying on the Ansatz that they can be predicted in the initial linear density field from the coalescence of critical points with…
Application of peaks theory to the abundance of primordial black holes
Sam Young, Marcello Musso
We consider the application of peaks theory to the calculation of the number density of peaks relevant for primordial black hole (PBH) formation. For PBHs, the final mass is relate…
Excursion set peaks in energy as a model for haloes
Marcello Musso, Ravi K. Sheth
The simplest models of dark matter halo formation are based on the heuristic assumption, motivated by spherical collapse, that virialized haloes originate from initial regions that…
How does the cosmic web impact assembly bias?
M. Musso, C. Cadiou, C. Pichon +3
The mass, accretion rate and formation time of dark matter haloes near proto-filaments (identified as saddle points of the potential) are analytically predicted using a conditional…
Large-scale assembly bias of dark matter halos
Titouan Lazeyras, Marcello Musso, Fabian Schmidt
We present precise measurements of the assembly bias of dark matter halos, i.e. the dependence of halo bias on other properties than the mass, using curved "separate universe" N-bo…
