Evolution equations dynamical system of the Lemaître--Tolman--Bondi metric containing coupled dark energy
Roberto C. Blanquet-Jaramillo, Roberto A. Sussman, Maximo Aguero +1
We consider inhomogeneous spherically symmetric models based on the Lemaître-Tolman-Bondi (LTB) metric, assuming as its source an interactive mixture of ordinary baryonic matter, c…
Primordial gravitational waves spectrum in the interacting Bose-Einstein gas model
German Izquierdo, Gildardo Alonzo, Jaime Besprosvany
We study the evolution and power spectrum of primordial gravitational waves in the interactive Bose-Einstein gas model for dark energy, relevant, as it addresses the coincidence pr…
Observational constraints on the free parameters of an interacting Bose-Einstein gas as a dark-energy model
Hiram E. Lucatero--Villaseñor, German Izquierdo, Jaime Besprosvany
Dark energy is modelled by a Bose-Einstein gas of particles with an attractive interaction. It is coupled to cold dark matter, within a flat universe, for the late-expansion descri…
Interactive mixture of inhomogeneous dark fluids driven by dark energy: a dynamical systems analysis
Germán Izquierdo, Roberto C Blanquet-Jaramillo, Roberto A Sussman
We examine the evolution of an inhomogeneous mixture of non-relativistic pressureless cold dark matter (CDM), coupled to dark energy (DE) characterised by the equation of state par…
Dynamics of a spherically symmetric inhomogeneous coupled dark energy model with coupling term proportional to non relatvistic matter
German Izquierdo, Roberto C. Blanquet-Jaramillo, Roberto A. Sussman
Quasi--local scalar variables approach is applied to a spherically symmetric inhomogeneous Lema\^ıtre--Tolman--Bondi metric containing a mixture of non-relativistic cold dark matte…
Numerical study of the Kerr solution in rotating coordinates
S. Bai, G. Izquierdo, C. Klein
The Kerr solution in coordinates corotating with the horizon is studied as a testbed for a spacetime with a helical Killing vector in the Ernst picture. The solution is numerically…
