A quantum cosmological model in Hořava-Lifshitz gravity
O. Obregón, J. A. Preciado
A Wheeler-DeWitt equation for the Kantowski-Sachs model is derived within the framework of the minimal quantum gravity theory proposed by Hořava. We study the solution to this equa…
Cosmological constraints in a two branes system for a vacuum bulk
Juan L. Perez, L. Arturo Urena-Lopez, Ruben Cordero
We present the study of a two 3-branes system embedded in a 5-dimensional space-time in which the fifth dimension is compacted on a orbifold and the space between the…
Conformal diagrams for the gravitational collapse of a spherically symmetric dust cloud
Néstor Ortiz, Olivier Sarbach
We present an algorithm for the construction of conformal coordinates in the interior of a spherically symmetric, collapsing matter cloud in general relativity. This algorithm is b…
Relativistic Processes and the Internal Structure of Neutron Stars
D. E. Alvarez-Castillo, S. Kubis
Models for the internal composition of Dense Compact Stars are reviewed as well as macroscopic properties derived by observations of relativistic processes. Modeling of pure neutro…
Quantum string cosmology in the phase space
Ruben Cordero, Erik Diaz, Hugo Garcia-Compean +1
Deformation quantization is applied to quantize gravitational systems coupled with matter. This quantization procedure is performed explicitly for quantum cosmology of these system…
Constraining scalar field properties with boson stars as black hole mimickers
J. Barranco, A. Bernal
Constraints to the mass of a scalar field and the strength of its self-interacting coupling constant are obtained. This was done using observations of stellar dynamics at the cente…
