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…
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.…
