Frequency shift of light emitted from growing and shrinking black holes
F. S. Guzman, I. Alvarez-Rios, J. A. Gonzalez
In this paper we present a method to study the frequency shift of signals sent from near a Schwarzschild black hole that grows or shrinks through accretion. We construct the numeri…
Solitons and instantons in vacuum stability: physical phenomena
J. A. Gonzalez, A Bellorin, L E Guerrero +3
In a previous paper [JCAP06, 033 (2018)] we have proved that it is possible to have a stable false vacuum in a potential that is unbounded from below. In this paper we discuss the…
Classification of a black hole spin out of its shadow using support vector machines
J. A. Gonzalez, F. S. Guzman
We use Support Vector Machines (SVMs) to classify the spin of a black hole. The SVMs are trained and tested with a catalog of numerically generated images of black holes, assuming…
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…
Fate of the true-vacuum bubbles
J. A. González, A. Bellorín, Mónica A. García-Ñustes +4
We investigate the bounce solutions in vacuum decay problems. We show that it is possible to have a stable false vacuum in a potential that is unbounded from below.
Behavior of luminous matter in the head-on encounter of two ultralight BEC dark matter halos
F. S. Guzman, J. A Gonzalez, J. P. Cruz
Within the context of ultralight BEC dark matter, we analyze the head-on encounters of two structures. These structures are made of a BEC component, which is a ground state equilib…
