On the growth of supermassive black holes formed from the gravitational collapse of fermionic dark matter cores
C. R. Argüelles, K. Boshkayev, A. Krut +5
Observations support the idea that supermassive black holes (SMBHs) power the emission at the center of active galaxies. However, contrary to stellar-mass BHs, there is a poor unde…
The Role of Self Interactions in the Cosmological Evolution of Warm Dark Matter
Rafael Ignacio Yunis, Carlos R. Argüelles, Diana López Nacir +3
In this work we present a summary of recent studies on the effects of elastic self interactions in the evolution of Warm Dark Matter models (WDM), focusing on structure formation a…
Reshaping our understanding on structure formation with the quantum nature of the dark matter
Carlos R. Argüelles, Eduar A. Becerra-Vergara, Andreas Krut +3
We study the non-linear structure formation in cosmology accounting for the quantum nature of the dark matter (DM) particles in the initial conditions at decoupling, as well as in…
Self-Interacting Dark Matter in Cosmology: accurate numerical implementation and observational constraints
Rafael Yunis, Carlos R. Argüelles, Claudia G. Scóccola +2
This paper presents a systematic and accurate treatment of the evolution of cosmological perturbations in self-interacting dark matter models, for particles which decoupled from th…
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…
Galactic Center constraints on self-interacting sterile neutrinos from fermionic dark matter ("ino") models
R. Yunis, C. R. Argüelles, N. E. Mavromatos +5
The neutrino minimal standard model (MSM) has been tightly constrained in the recent years, either from dark matter (DM) production or from X-ray and small-scale observations. H…
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…
