A class of static spherically symmetric solutions in -gravity
Marco Calzá an Lorenzo Sebastiani
We study a class of static spherically symmetric vacuum solutions in modified teleparallel gravity solving the field equations for a specific model Ansatz, requiring the torsion sc…

Kinematic reconstructions of extended theories of gravity at small and intermediate redshifts
Marco Calzà, Alessandro Casalino, Orlando Luongo +1
In the last few decades, extensions of General Relativity have reached always more attention especially in view of possible breakdowns of the standard CDM paradigm at intermedia…

A special class of solutions in -gravity
Marco Calzà, Massimiliano Rinaldi, Lorenzo Sebastiani
We consider a special class of vacuum -modified gravity models. The form of their Lagrangian is such that the field equations are trivially satisfied when the Ricci scalar is…
