On the formation and stability of fermionic dark matter halos in a cosmological framework
Carlos R. Argüelles, Manuel I. Díaz, Andreas Krut +1
The formation and stability of collisionless self-gravitating systems are long standing problems, which date back to the work of D. Lynden-Bell on violent relaxation and extends to…

Boltzmann hierarchies for self-interacting warm dark matter scenarios
Rafael Yunis, Carlos R. Argüelles, Diana López Nacir
We provide a general framework for self-interacting warm dark matter (WDM) in cosmological perturbations, by deriving from first principles a Boltzmann hierarchy which retains cert…

New constraints on sterile neutrino dark matter from the Galactic Center
R. Yunis, C. R. Argüelles, N. E. Mavromatos +4
We calculate the most stringent constraints up to date on the parameter space for sterile neutrino warm dark matter models possessing a radiative decay channel into X-rays. These c…
