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…
Galaxy Rotation Curve Fitting Using Machine Learning Tools
Carlos R. Argüelles, Santiago Collazo
Galaxy rotation curve (RC) fitting is an important technique which allows the placement of constraints on different kinds of dark matter (DM) halo models. In the case of non-phenom…
Fermionic Dark Matter: Physics, Astrophysics, and Cosmology
C. R. Argüelles, E. A. Becerra-Vergara, J. A. Rueda +1
The nature of dark matter (DM) is one of the most relevant questions in modern astrophysics. We present a brief overview of recent results that inquire into a possible fermionic qu…
Galaxy rotation curves and universal scaling relations: comparison between phenomenological and fermionic dark matter profiles
A. Krut, C. R. Argüelles, P. -H. Chavanis +2
Galaxies show different halo scaling relations such as the Radial Acceleration Relation, the Mass Discrepancy Acceleration Relation (MDAR) or the dark matter Surface Density Relati…
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…
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…
Fermionic Halos at Finite Temperature in AdS/CFT
Carlos R. Argüelles, Nicolás E. Grandi
We explore the gravitational backreaction of a system consisting in a very large number of elementary fermions at finite temperature, in asymptotically AdS space. We work in the hy…
Strong lensing by fermionic dark matter in galaxies
L. Gabriel Gómez, C. R. Argüelles, Volker Perlick +2
It has been shown that a self-gravitating system of massive keV fermions in thermodynamic equilibrium correctly describes the dark matter (DM) distribution in galactic halos and pr…
Novel constraints on fermionic dark matter from galactic observables I: The Milky Way
C. R. Argüelles, A. Krut, J. A. Rueda +1
We have recently introduced a new model for the distribution of dark matter (DM) in galaxies based on a self-gravitating system of massive fermions at finite temperatures, the Ruff…
Complete Classification of Four-Dimensional Black Hole and Membrane Solutions in IR-modified Hořava Gravity
Carlos Argüelles, Nicolás Grandi, Mu-In Park
Hořava gravity has been proposed as a renormalizable, higher-derivative gravity without ghost problems, by considering different scaling dimensions for space and time. In the non-r…
The role of self-interacting right-handed neutrinos in galactic structure
C. R. Argüelles, N. E. Mavromatos, J. A. Rueda +1
It has been shown previously that the DM in galactic halos can be explained by a self-gravitating system of massive keV fermions (`inos') in thermodynamic equilibrium, and predicte…

R. Ruffini, C. R. Argüelles, J. A. Rueda
We investigate the distribution of dark matter in galaxies by solving the equations of equilibrium of a self-gravitating system of massive fermions (`inos') at selected temperature…

Carlos R. Argüelles, Remo Ruffini
Essay selected for Honorable mention 2014 by the Gravity Research Foundation. We study an isothermal system of semi-degenerate self-gravitating fermions in General Relativity (GR).…
Critical configurations for a system of semidegenerate fermions
Carlos R. Argüelles, Remo Ruffini, Bernardo M. O. Fraga
We study an isothermal system of semi-degenerate self-gravitating fermions in general relativity. Such systems present mass density solutions with a central degenerate core, a plat…
On the distribution of dark matter in galaxies: quantum treatments
Carlos R. Argüelles, Remo Ruffini, Ivan Siutsou +1
The problem of modeling the distribution of dark matter in galaxies in terms of equilibrium configurations of collisionless self-gravitating quantum particles is considered. We fir…
Dark Matter Massive Fermions and Einasto Profiles in Galactic Haloes
I. Siutsou, C. R. Argüelles, R. Ruffini
On the basis of a fermionic dark matter model we fit rotation curves of The HI Nearby Galaxy Survey THINGS sample and compare our 3-parametric model to other models widely used in…
