The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …

We work out the junction conditions for the Palatini f (R, T) extension of general relativity,
where f is an arbitrary function of the curvature scalar R of an independent connection, and …

We discuss some general and relevant features of longitudinal gravitational modes in
Horndeski gravity and their interaction with matter media. Adopting a gauge-invariant …

We study a metric-affine gravitational theory given by the Einstein–Hilbert (EH) action plus a
parity violating contribution (which we will refer to as the Hojman term, also known as Holst …

This thesis covers several developments performed in metric-affine gravity. This alternative
framework extends General Relativity by considering a more general connection than the …

We study a spin 1/2 fermion in a thick braneworld in the context of teleparallel f (T, B) gravity.
Here, f (T, B) is such that f_1 (T, B)= T+ k_1B^ n_1 f 1 (T, B)= T+ k 1 B n 1 and f_2 (T, B)= B+ …

We state and prove a simple theorem that allows one to generate invariant quantities in
metric-affine geometry, under a given transformation of the affine connection. We start by a …

The present paper revisits conventionalism about the geometry of classical and relativistic
spacetimes. By means of critically examining a recent evaluation of conventionalism, we …

In the context of f (R) generalizations to the Holst action, endowed with a dynamical Immirzi
field, we derive an analytic solution describing asymptotically anti–de Sitter black holes with …

First, we propose a scale-invariant modified gravity interacting with a neutral scalar inflaton
and a Higgs-like SU (2)× U (1) iso-doublet scalar field based on the formalism of non …
