Iron K signatures from accretion disks around fermionic dark matter cores
V. Crespi, F. L. Vieyro, C. R. Argüelles +1
The fluorescent iron line and its broadening due to relativistic effects are excellent probes to study the inner part of an accretion disk and the space-time geometry near the comp…

Modelling the Track of the GD-1 Stellar Stream Inside a Host with a Fermionic Dark Matter Core-Halo Distribution
Martín F. Mestre, Carlos R. Argüelles, Daniel D. Carpintero +2
Traditional studies on stellar streams typically involve phenomenological CDM halos or ad hoc dark matter (DM) profiles with different degrees of triaxiality, which preclude to…

Baryon-induced collapse of dark matter cores into supermassive black holes
C. R. Arguelles, J. A. Rueda, R. Ruffini
Non-linear structure formation for fermionic dark matter particles leads to dark matter density profiles with a degenerate compact core surrounded by a diluted halo. For a given fe…
