Constraining the effective field theory of dark energy with multimessenger astronomy
Antonio Enea Romano
The effective field theory of dark energy predicts a possible time variation of the propagation speed of gravitational waves (GW) which could be tested with multimessenger astronom…
The mirage of luminal modified gravitational-wave propagation
Antonio Enea Romano, Mairi Sakellariadou
Using conformal invariance of gravitational waves, we show that for a luminal modified gravity theory, the gravitational-wave propagation and luminosity distance are the same as in…
Gravitoelectromagnetic quadrirefringence
Antonio Enea Romano, Sergio A. Vallejo-Peña
We develop an effective approach for the study of the interaction of gravitational waves (GWs) and electromagnetic waves (EMWs), showing that quadrirefringence can be produced, a p…
Effective speed of cosmological perturbations
Antonio Enea Romano
We derive an effective equation and action for comoving curvature perturbations and gravitational waves (GWs) in terms of a time, momentum and polarization dependent effective spee…
