Basement structures over Rio Grande Rise from gravity inversion
(2017-04-01)
The basement depth in the Rio Grande Rise (RGR), South Atlantic, is estimated from combining gravity data obtained from satellite altimetry, marine surveys, bathymetry, sediment thickness and crustal thickness information. ...
Slow-roll inflation in f(R,T) gravity and a modified Starobinsky-like inflationary model
(2021)
In this work, we studied the slow-roll approximation of cosmic inflation within the context of f (R,T) gravity, where R is the scalar curvature, and T is the trace of the energy-momentum tensor. By choosing a minimal ...
A novel teleparallel dark energy model
(2016-02-01)
Although equivalent to general relativity, teleparallel gravity (TG) is conceptually speaking a completely different theory. In this theory, the gravitational field is described by torsion, not by curvature. By working in ...
A topological-like model for gravity in 4D space-time
(The European Physical Journal C, 2019)
Minimal Log Gravity
(American Physical Society, 2015-01)
Minimal Massive Gravity (MMG) is an extension of three-dimensional Topologically Massive Gravity that, when formulated about Anti-de Sitter space, accomplishes to solve the tension between bulk and boundary unitarity that ...
Braneworlds scenarios in a gravity model with higher order spatial three-curvature terms
(Springer, 2013-04-04)
Reconstruction of f(r, t) gravity describing matter dominated and accelerated phases
(2012)
We investigate the cosmological reconstruction in modified f(R, T) gravity, where R is the Ricci scalar and T the trace of the stress–energy tensor. Special attention is attached to the case in which the function f is given ...
