Observational constraints for cubic gravity theory based on third order contractions of the Riemann tensor

Mihai Marciu, Dana Maria Ioan, Mihai Dragomir

The paper studies different observational features in the case of a specific cubic gravity theory, based on third order contractions of the Riemann tensor. Considering viable cosmi…

The accelerated expansion in $F (G, T_{μν} T^{μν})$ gravity

Mihai Marciu, Dana Maria Ioan

In the present manuscript the basic Einstein--Hilbert cosmological model is extended, by adding a new functional $F (G, T_{μν} T^{μν})$ in the fundamental action, encoding specific g…

Physical aspects of $f (R, G_{μν} T^{μν})$ modified gravity theories

Mihai Marciu, Dana Maria Ioan

The paper extends basic Einstein--Hilbert action by adding a newly proposed invariant constructed from a specific contraction between the Einstein tensor and the energy momentum te…
