Thermodynamical and dynamical equilibrium of a self-gravitating uncharged thin shell
Santiago Esteban Perez Bergliaffa, Marcelo Chiapparini, Luz Marina Reyes
The dynamical stability of massive thin shells with a given equation of state (EOS) is here compared (both for the barotropic and non-barotropic case) with the results coming from…
On the emergence of the CDM model from self-interacting Brans-Dicke theory in
Luz Marina Reyes, Santiago Esteban Perez Bergliaffa
We investigate whether a self-interacting Brans-Dicke theory in without matter and with a time-dependent metric can describe, after dimensional reduction to , the FLRW m…
Scalar fluctuations of the scalar metric during inflation from a non-perturbative 5D large-scale repulsive gravity model
José Edgar Madriz Aguilar, Luz Marina Reyes, Claudia Moreno +1
We develop a non-perturbative formalism for scalar metric fluctuations from a 5D extended version of general relativity in vacuum. In this work we concentrate our efforts on calcul…
Gravitational waves during inflation from a 5D large-scale repulsive gravity model
Luz Marina Reyes, Claudia Moreno, José Edgar Madriz Aguilar +1
We investigate, in the transverse traceless (TT) gauge, the generation of the relic background of gravitational waves, generated during an early inflationary stage, on the framewor…
On gravitational waves generated during inflation under the influence of a dynamical cosmological "constant"
Reyes Luz Marina, Moreno Claudia, Madriz Aguilar Jose Edgar
We study cosmological gravitational waves generated during inflation under the influence of a decaying cosmological "constant", in the Transverse-Traceless (TT) gauge. In our appro…
Cosmological dark fluid from five-dimensional vacuum
Luz M. Reyes, José Edgar Madriz Aguilar, L Arturo Ureña-López
In the framework of the induced matter theory of gravity, we derive a 5D solution of the field equations that can describe a 4D cosmological scenario where the dark fluid (dark mat…
