Merger of galactic cores made of ultralight bosonic dark matter
F. S. Guzman, J. A. Gonzalez, I. Alvarez-Rios
We study binary mergers of ultralight bosonic dark matter cores by solving the Gross-Pitaevskii-Poisson system of equations. The analysis centers on the dynamics of the relaxation…
Estimation of Reynolds number for flows around cylinders with lattice Boltzmann methods and artificial neural networks
Mauricio Carrillo, Ulices Que, José A. González
The present work investigates the application of Artificial Neural Networks (ANNs) to estimate the Reynolds () number for flows around a cylinder. The data required to train th…
Recognition of an obstacle in a flow using artificial neural networks
Mauricio Carrillo, Ulices Que, José A. González +1
In this work a series of artificial neural networks (ANNs) have been developed with the capacity to estimate an obstacle's size and location obstructing the flow in a pipe. The ANN…
Study of simulated Bloch oscillations in strained graphene using neural networks
J. A. González, C. E. López, A. Raya
We consider a monolayer of graphene under uniaxial, tensile strain and simulate Bloch oscillations for different electric field orientations parallel to the plane of the monolayer…
Bloch oscillations in two-dimensional crystals: Inverse problem
M Carrillo, J A González, S Hernández +2
Within an artificial neural network (ANN) approach, we classify simulated signals corresponding to the semi-classical description of Bloch oscillations on a two-dimensional square…
Bloch oscillations: Inverse problem
José Antonio González, Saúl Hernández Ortiz, Carlos Eduardo López +1
We use a neural network approach to explore the inverse problem of Bloch oscillations in a monoatomic linear chain: given a signal describing the path of oscillations of electrons…
Parameter estimates in binary black hole collisions using neural networks
M. Carrillo, M. Gracia-Linares, J. A. González +1
We present an algorithm based on artificial neural networks (ANNs), that estimates the mass ratio in a binary black hole collision out of given Gravitational Wave (GW) strains. In…
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…
On the instability of charged wormholes supported by a ghost scalar field
J. A. Gonzalez, F. S. Guzman, O. Sarbach
In previous work, we analyzed the linear and nonlinear stability of static, spherically symmetric wormhole solutions to Einstein's field equations coupled to a massless ghost scala…

J. A. Gonzalez, F. S. Guzman, N. Montelongo-Garcia +1
By a combination of analytical and numerical techniques, we demonstrate the existence of spherical, asymptotically flat traversable wormholes supported by exotic matter whose stres…
Accretion of phantom scalar field into a black hole
J. A. Gonzalez, F. S. Guzman
Using numerical methods we present the first full nonlinear study of phantom scalar field accreted into a black hole. We study different initial configurations and find that the ac…

J. A. Gonzalez, F. S. Guzman, O. Sarbach
We analyze the nonlinear evolution of spherically symmetric wormhole solutions coupled to a massless ghost scalar field using numerical methods. In a previous article we have shown…

J. A. Gonzalez, F. S. Guzman, O. Sarbach
We examine the linear stability of static, spherically symmetric wormhole solutions of Einstein's field equations coupled to a massless ghost scalar field. These solutions are para…
