gravity in the Jordan Frame as a Paradigm for the Hubble Tension
Tiziano Schiavone, Giovanni Montani, Flavio Bombacigno
We analyse the gravity in the so-called Jordan frame, as implemented to the isotropic Universe dynamics. The goal of the present study is to show that, according to recent d…
Landau damping for gravitational waves in parity-violating theories
Flavio Bombacigno, Fabio Moretti, Simon Boudet +1
We discuss how tensor polarizations of gravitational waves can suffer Landau damping in the presence of velocity birefringence, when parity symmetry is explicitly broken. In partic…
Torsional birefringence in metric-affine Chern-Simons gravity: gravitational waves in late-time cosmology
S. Boudet, F. Bombacigno, F. Moretti +1
In the context of the metric-affine Chern-Simons gravity endowed with projective invariance, we derive analytical solutions for torsion and nonmetricity in the homogeneous and isot…
Quasinormal modes of Schwarzschild black holes in projective invariant Chern-Simons modified gravity
Simon Boudet, Flavio Bombacigno, Gonzalo J. Olmo +1
We generalize the Chern-Simons modified gravity to the metric-affine case and impose projective invariance by supplementing the Pontryagin density with homothetic curvature terms w…
Quasinormal modes of Schwarzschild black holes in metric affine Chern-Simons theory
Flavio Bombacigno
We reformulate the Chern-Simons modified gravity in the metric-affine formalism, by enlarging the Pontryagin density with homothetic curvature terms which restore projective invari…
