The Tidal Torque Theory Revisited: II. Rotational Halo Properties

Eduard Salvador-Solé, Alberto Manrique

The peak model of structure formation was built more than fifty years ago with the aim to address the origin of dark matter halo rotation in the tidal torque theory (TTT). Paradoxi…

An Accurate Comprehensive Approach to Substructure: IV. Dynamical Friction

Eduard Salvador-Solé, Alberto Manrique, Andreu Rocamora

In three previous Papers we analysed the origin of the properties of halo substructure found in simulations. This was achieved by deriving them analytically in the peak model of st…

The Tidal Torque Theory Revisited. I. Protohalo Angular Momentum

Eduard Salvador-Solé, Alberto Manrique

In the tidal-torque theory, the angular momentum (AM) of dark matter halos arises from the tidal torque suffered by aspherical collapsing patches due to surrounding mass fluctuatio…

Origin and full characterization of the secondary (assembly) halo bias

Eduard Salvador-Solé, Alberto Manrique, Eduard Agulló

The clustering of dark matter halos depends not only on their mass, the so-called primary bias, but also on their internal properties, the so-called secondary bias. While the forme…

Halo bias in the peak model. A first-principles non-parametric approach

Eduard Salvador-Solé, Alberto Manrique

The Press-Schechter (PS) and excursion set (ES) models of structure formation fail in reproducing the halo bias found in simulations, while the excursion set-peaks (ESP) formalism…
