Parametrized post-Newtonian formalism in higher-order Teleparallel Gravity
Manuel Gonzalez-Espinoza, Giovanni Otalora, Lucila Kraiselburd +1
We study the parametrized post-Newtonian (PPN) limit of higher-derivative-torsion Modified Teleparallel Gravity. We start from the covariant formulation of modified Teleparallel Gr…

Testing f(R) gravity models with quasar X-ray and UV fluxes
Matías Leizerovich, Lucila Kraiselburd, Susana J. Landau +1
Recently, Active Galactic Nuclei (AGNs) have been proposed as standardizable candles, thanks to an observed non-linear relation between their X-ray and optical-ultraviolet (UV) lum…
