Spiral galaxies rotation curves in the Horava - Lifshitz gravity theory
Vincenzo F. Cardone, Monica Capone, Ninfa Radicella +1
We focus on a modified version of Horava - Lifschitz theory and, in particular, we consider the impact of its weak - field static spherically symmetric limit on the galaxy dynamics…
The Milky Way rotation curve in Horava - Lifshitz theory
V. F. Cardone, N. Radicella, M. L. Ruggiero +1
The Horava - Lifshitz (HL) theory has recently attracted a lot of interest as a viable solution to some quantum gravity related problems and the presence of an effective cosmologic…
Jumping from Metric f(R) to Scalar-Tensor Theories and the relations between their post-Newtonian Parameters
Monica Capone, Matteo Luca Ruggiero
We review the dynamical equivalence between gravity in the metric formalism and scalar-tensor gravity, and use this equivalence to deduce the post-Newtonian parameters a…
Accelerating cosmology in Rastall's theory
Monica Capone, Vincenzo Fabrizio Cardone, Matteo Luca Ruggiero
In an attempt to look for a viable mechanism leading to a present-day accelerated expansion, we investigate the possibility that the observed cosmic speed up may be recovered in th…
Fitting the luminosity data from type Ia supernovae in the frame of the Cosmic Defect theory
A. Tartaglia, M. Capone, V. Cardone +1
The Cosmic Defect (CD) theory is reviewed and used to fit the data for the accelerated expansion of the universe, obtained from the apparent luminosity of 192 SnIa's. The fit from…
Slow rolling, inflation and quintessence
M. Capone, C. Rubano, P. Scudellaro
We comment on the choice of the quintessence potential, examining the slow-roll approximation in a minimally coupled theory of gravity. We make some considerations on the potential…
