Inflation and Primordial Fluctuations in Gravity's Rainbow
Yoelsy Leyva, Carlos Leiva, Giovanni Otalora +1
We study slow-roll inflation and the generation of primordial fluctuations in gravity's rainbow. We obtain the second order action for scalar and tensor perturbations and th…
Shadow cast of non-commutative black holes in Rastall gravity
Ali Övgün, İzzet Sakallı, Joel Saavedra +1
We study the shadow and energy emission rate of a spherically symmetric non-commutative black hole in Rastall gravity. Depending on the model parameters, the non-commutative black…
Snyder Like Modified Gravity in Newton's Spacetime
Carlos Leiva
This work is focused on searching a geodesic interpretation of the dynamics of a particle under the effects of a Snyder like deformation in the background of the Kepler problem. In…
Some features of a Schwarzchild Black Hole from a Snyder perspective
Carlos Leiva
In this paper, the consequences of introducing a deformed Snyder-Kepler potential in the Schwarzchild metric are investigated. After this modification, it is obtained a dynamically…
Thawing models in the presence of a generalized Chaplygin gas
Sergio del Campo, Carlos R. Fadragas, Ramon Herrera +3
In this paper we consider a cosmological model whose main components are a scalar field and a generalized Chaplygin gas. We obtain an exact solution for a flat arbitrary potential.…
The Kepler problem in the Snyder space
Carlos Leiva, Joel Saavedra, J. R. Villanueva
In this paper we study the Kepler problem in the non commutative Snyder scenario. We characterize the deformations in the Poisson bracket algebra under a mimic procedure from quant…
