Gravitational production of scalar dark matter
Jose A. R. Cembranos, Luis J. Garay, Jose M. Sánchez Velázquez
We investigate the gravitational production of scalar dark matter particles during the inflationary and reheating epochs. The oscillatory behavior of the curvature scalar durin…
Fate of scalar dark matter solitons around supermassive galactic black holes
Philippe Brax, Jose A. R. Cembranos, Patrick Valageas
In scalar-field dark matter scenarios, a scalar-field soliton could form at the center of galactic halos, around the supermassive black holes that sit at the center of galaxies. Fo…
Impact of kinetic and potential self-interactions on scalar dark matter
Philippe Brax, Jose A. R. Cembranos, Patrick Valageas
We consider models of scalar dark matter with a generic interaction potential and non-canonical kinetic terms of the K-essence type that are subleading with respect to the canonica…
Double SU(4) model
Jose A. R. Cembranos, Pablo Diez-Valle
In this manuscript we study the Double SU(4) model as a grand unified theory based on the gauge group . A complete set of gene…
Non-geodesic incompleteness in Poincaré gauge gravity
J. A. R. Cembranos, J. Gigante Valcarcel, F. J. Maldonado Torralba
In this work we review the study of singularities in Poincaré gauge theories of gravity. Since one of the most recent studies uses the appearance of black hole regions of arbitrary…
