Hinting a dark matter nature of Sgr A* via the S-stars
E. A. Becerra-Vergara, C. R. Argüelles, A. Krut +2
The motion data of the S-stars around the Galactic center gathered in the last 28 yr imply that Sgr A* hosts a supermassive compact object of about , a resul…
The geodesic motion of S2 and G2 as a test of the fermionic dark matter nature of our galactic core
E. A. Becerra-Vergara, C. R. Arguelles, A. Krut +2
[Abridged] The S-stars motion around the Galactic center (Sgr A*) implies the existence of a compact source with a mass of about , traditionally assumed to be…
Thermodynamic instabilities in holographic neutron stars at finite temperature
Carlos R. Argüelles, Tobías Canavesi, Manuel Díaz +1
We study the thermodynamics of a self-gravitating system of neutral fermions at finite temperature and analyze its backreaction in an asymptotically AdS space. We evaluate numerica…
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…
Novel constraints on fermionic dark matter from galactic observables II: galaxy scaling relations
C. R. Argüelles, A. Krut, J. A. Rueda +1
We have recently introduced in paper I an extension of the Ruffini-Argüelles-Rueda (RAR) model for the distribution of DM in galaxies, by including for escape of particle effects.…
