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…
Getting in shape with minimal energy. A variational principle for protohaloes
Marcello Musso, Ravi K. Sheth
In analytical models of structure formation, protohalos are routinely assumed to be peaks of the smoothed initial density field, with the smoothing filter being spherically symmetr…
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…
The impact of the connectivity of the cosmic web on the physical properties of galaxies at its nodes
Katarina Kraljic, Christophe Pichon, Sandrine Codis +11
We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We co…
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…
