Cosmology from a new non-conservative gravity
Júlio C. Fabris, Hermano Velten, Thiago R. P. Caramês +2
In this paper we present a cosmological model arising from a non-conservative gravitational theory proposed in [PRD 95, 101501(R) (2017)]. The novel feature where comparing with pr…
global monopole revisited
Thiago R. P. Caramês, Júlio C. Fabris, E. R. Bezerra de Mello +1
In this paper the global monopole is reexamined. We provide an exact solution for the modified field equations in the presence of a global monopole for regions outside its c…
Reply to Comment [arXiv:1707.00747] by P. H. R. S. Moraes, R. A. C. Correa and G. Ribeiro on "Cosmological inviability of gravity" [H. Velten and Thiago R. P. Caramês, Phys. Rev. D 95 (2017) 123536, arXiv:1702.07710]
Hermano Velten, Thiago Carames
In this Reply we reassert the failure of the model in providing a transition from deceleration to an accelerated stage as we have pointed out in [H. Velten and…
Cosmological inviability of gravity
Hermano Velten, Thiago R. P. Caramês
Among many alternative gravitational theories to General Relativity (GR), gravity (where is the Ricci scalar and the trace of the energy-momentum tensor) has been…
