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…
