On the shape of pancakes: catastrophe theory and Gaussian statistics in 2D
Abineet Parichha, Stephane Colombi, Shohei Saga +1
Cold dark matter (CDM) can be thought of as a 2D (or 3D) sheet of particles in 4D (or 6D) phase-space due to its negligible velocity dispersion. The large-scale structure, also cal…
Post-collapse Lagrangian perturbation theory in three dimensions
Shohei Saga, Stéphane Colombi, Atsushi Taruya +2
The gravitational collapse of collisionless matter leads to shell-crossing singularities that challenge the applicability of standard perturbation theory. Here, we present the firs…
Dark matter halo dynamics in 2D Vlasov Simulations: a self-similar approach
Abineet Parichha, Stephane Colombi, Shohei Saga +1
Understanding dark matter halo dynamics can be pivotal in unravelling the nature of dark matter particles. Analytical treatment of the multistream flows inside the turnaround regio…
WIMP decay as a possible Warm Dark Matter model
Abineet Parichha, Shiv Sethi
The Weakly Interacting Massive Particles(WIMPs) have long been the favored CDM candidate in the standard CDM model. However, owing to great improvement in the experimental sensi…
