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…
On the linear and non linear evolution of the RMHD Kelvin Helmholtz instability in a magnetically polarized fluid
Oscar M. Pimentel, F. D. Lora-Clavijo
The origin of the magnetic field in some systems like AGNs or GRBs is still an open question in astrophysics. A possible mechanism to explain the magnetic field generation is the K…
Analytic solution of a magnetized tori with magnetic polarization around Kerr black holes
Oscar M. Pimentel, F. D. Lora-Clavijo, Guillermo A. Gonzalez
We present the first family of magnetically polarized equilibrium tori around a Kerr black hole. The models were obtained in the test fluid approximation by assuming that the tori…
Numerical general relativistic MHD with magnetically polarized matter
Oscar M. Pimentel, F. D. Lora-Clavijo, Guillermo A. González
The magnetically polarized matter in astrophysical systems may be relevant in some magnetically dominated regions. For instance, the funnel that is generated in some highly magneti…
