Synchrotron emitting Komissarov torus with magnetic polarization around Kerr black holes
J. M. Velásquez-Cadavid, Fabio D. Lora-Clavijo, Oscar M. Pimentel +1
Magnetic fields in black hole accretion disks are associated with processes of mass accretion and energy amplification. The contribution of the magnetic field due to the magnetic p…
OSIRIS: A New Code for Ray Tracing Around Compact Objects
Velásquez-Cadavid J. M., Arrieta-Villamizar J. A., F. D. Lora-Clavijo +2
The radiation observed in quasars and active galactic nuclei is mainly produced by a relativistic plasma orbiting close to the black hole event horizon, where strong gravitational…
Shadows around the q-metric
J. A. Arrieta-Villamizar, J. M. Velásquez-Cadavid, O. M. Pimentel +2
One crucial problem in relativistic astrophysics is that of the nature of black hole candidates. It is usually assumed that astrophysical black holes are described by the Schwarzsc…
Ideal Magnetohydrodynamics with Radiative Terms: Energy Conditions
Oscar M. Pimentel, F. D. Lora-Clavijo, Guillermo A. González
Nowadays, the magnetic and radiation fields are very important to understand the matter accretion into compact objects, the dynamics of binary systems, the equilibrium configuratio…
The Energy-Momentum Tensor for a Dissipative Fluid in General Relativity
Oscar M. Pimentel, Guillermo A. González, F. D. Lora-Clavijo
Considering the growing interest of the astrophysicist community in the study of dissipative fluids with the aim of getting a more realistic description of the universe, we present…
Static Thin Disks with Haloes as Sources of Conformastatic Spacetimes
Guillermo A. González, Oscar M. Pimentel
Two new families of exact solutions to the Einstein equations for a conformastatic spacetime with axial symmetry are presented which describe thin disks of dust immersed in a spher…
