Characterizing the velocity of a wandering black hole and properties of the surrounding medium using convolutional neural networks
J. A. Gonzalez, F. S. Guzman
We present a method for estimating the velocity of a wandering black hole and the equation of state for the gas around, based on a catalog of numerical simulations. The method uses…
Evolution of jets driven by relativistic radiation hydrodynamics as Long and Low Luminosity GRBs
F. J. Rivera-Paleo, F. S. Guzmán
We present the three-dimensional numerical simulation of jets modeled with Relativistic Radiation Hydrodynamics (RRH), that evolve across two environments: i) a stratified surround…
Modeling long GRBs using a single shock with relativistic radiation hydrodynamics
F. J. Rivera-Paleo, F. S. Guzman
We explore the possibility that a single relativistic shock, where the gas dynamics is coupled with radiation, can fit the light curves of long GRBs. For this we numerically solve…
Accretion of supersonic winds onto black holes in 3D: stability of the shock cone
M. Gracia-Linares, F. S. Guzman
Using numerical simulations we present the accretion of supersonic winds onto a rotating black hole in three dimensions. We study five representative directions of the wind with re…
The shocks during the accretion of an ultrarelativistic supersonic gas onto a rotating black hole
A. Cruz-Osorio, F. D. Lora-Clavijo, F. S. Guzman
In this work, we track the evolution of an ultrarelativistic fluid onto a Kerr black hole, on the equatorial plane. In this treatment, we consider the limit where the rest mass den…
Exact solution of the 1D Riemann problem in Newtonian and relativistic hydrodynamics
F. D. Lora-Clavijo, J. P. Cruz-Perez, F. S. Guzman +1
Some of the most interesting scenarios that can be studied in astrophysics, contain fluids and plasma moving under the influence of strong gravitational fields. To study these prob…
Axisymmetric Bondi-Hoyle accretion onto a Schwarzschild Black Hole: shock cone vibrations
F. D. Lora-Clavijo, F. S. Guzman
We study numerically the axisymmetric relativistic Bondi-Hoyle accretion of a supersonic ideal gas onto a fixed Schwarzschild background space-time described with horizon penetrati…
Is the flip-flop behaviour of accretion shock cones on to black holes an effect of coordinates?
A. Cruz-Osorio, F. D. Lora-Clavijo, F. S. Guzman
We study numerically the relativistic Bondi-Hoyle accretion of an ideal gas onto a Kerr fixed background space-time on the equatorial plane with s-lab symmetry. We use both Kerr-Sc…
Spherical Boson Stars as Black Hole mimickers
F. S. Guzman, J. M. Rueda-Becerril
We present spherically symmetric boson stars as black hole mimickers based on the power spectrum of a simple accretion disk model. The free parameters of the boson star are the mas…
