Cosmological study of some S-brane solutions in M-theory
J. A. Agudelo, H. I. Arcos, A. Idarraga
A cosmological analysis considering the inclusion of dark energy and dark matter cosmic components in the context of some particular cases for intersecting S-brane solutions is pre…
Exploring Higher-Order Gravitational Waves
H. Arcos, M. Krssak, J. G. Pereira
In addition to the usual linear gravitational waves in transverse-traceless coordinates, higher-order gravitational field equations, as well as their corresponding solutions, are e…
Spin-2 fields and helicity
H. I. Arcos, C. S. O. Mayor, G. Otalora +1
By considering the irreducible representations of the Lorentz group, an analysis of the different spin-2 waves is presented. In particular, the question of the helicity is discusse…
Consistent Gravitationally-Coupled Spin-2 Field Theory
H. I. Arcos, Tiago Gribl Lucas, J. G. Pereira
Inspired by the translational gauge structure of teleparallel gravity, the theory for a fundamental massless spin-2 field is constructed. Accordingly, instead of being represented…
Spacetime: Arena or Reality?
H. I. Arcos, J. G. Pereira
For small values of the mass (in relation to the angular momentum and electric charge), the Kerr-Newman (KN) solution of Einstein equation reduces to a naked singularity of circula…
De Sitter cosmology from Gauss-Bonnet dark energy with quantum effects
Emilio Elizalde, John Quiroga Hurtado, Hector Ivan Arcos
A Gauss-Bonnet dark energy model is considered, which is inspired in string/M-theory and takes also into account quantum contributions. Those are introduced from a conformal quantu…
