Cosmology: Galaxies – Angular Momentum – Large Scale Structure of the Universe

Introduction
============

In the current paradigm of large-scale structure formation in the Universe it is well established that the angular momentum of dark-matter (DM) halos is determined early in the history of the Universe by the gravitational interaction between the quadrupole of the collapsing proto-halo region and the surrounding matter. This was first formulated for the hierarchical theory of structure formation by @White1, @Doro1, and @Peebles1, and it is claimed that this is a natural consequence of the perturbative treatment of the gravitational instability scenario (@Porciani1). Several inherent properties to the tidal torque process (Tidal Torque Theory, TTT) have been noticed and studied in the literature. For instance it is expected from TTT, and also supported to some degree by N-body simulations, that the angular momentum starts growing linearly with time [@Catelan2; @Peebles1; @White1], and
