Revisiting relativistic electrically charged polytropic spheres
Andrés Aceña, Bruno Cardin Guntsche, Iván Gentile de Austria
We revisit the problem of the structure and physical properties of electrically charged static spherically symmetric solutions of the Einstein-Maxwell system of equations where the…
No-go theorem for static spherically symmetric configurations composed of two charged pressureless fluid species
Andrés Aceña, Bruno Cardin Guntsche, Ivan Gentile de Austria
We present a no-go theorem for spherically symmetric configurations of two charged fluid species in equilibrium. The fluid species are assumed to be dusts, that is, perfect fluids…
Thermodynamics sheds light on the nature of dark matter galactic halos
Andrés Aceña, Juan Barranco, Argelia Bernal +1
In spherical symmetry, the gravitational potential is uniquely determined by the rotational velocity profile. Numerous galaxies exhibit a universal velocity profile from which a un…
No-go theorem for static configurations of two charged dust species
Andrés Aceña, Bruno Cardin Guntsche, Ivan Gentile de Austria
We consider static spacetimes with no specific spacial symmetry where the matter content consists of two charged dust species. This comes motivated by the fact that static configur…
Preliminary Study on Dark Matter-Dominated Systems: Further Analysis for galactic dark matter halos with Pressure
Andrés Aceña, Juan Barranco, Argelia Bernal +2
Low surface brightness galaxies are an excellent laboratory where stars and baryonic matter act as tracers of the gravitational potential of the dark matter halo. If dark matter is…
Spherically symmetric linear perturbations of electrically counterpoised dust
Andrés Aceña, Ivan Gentile de Austria
We consider spherically symmetric linear perturbations of static spherically symmetric spacetimes where the matter content is ellectrically counterpoised dust. We show that the evo…
