Effective speed approach for modified scalar field propagation
Kevin Restrepo Tobón, Antonio Enea Romano
We study the propagation of a constant-speed Gaussian scalar field wave packet (GWP) in Minkowski space, showing that the energy conditions are violated for superluminal speeds. We…
The effects of dark energy on the matter-gravity coupling
Antonio Enea Romano
Dark energy perturbations are expected to modify the evolution of cosmological perturbations, producing different observational effects. We show that these effects can be encoded i…
Testing the consistency of gravitational waves and large scale structure constraints on dark energy
Antonio Enea Romano, Juan Manuel Cardenas Mancipe
Gravitational wave (GW) astronomy has opened a new window on the Universe, allowing to obtain constraints on dark energy and gravity independent from other electromagnetic waves ob…
Multimessenger consistency relations bridging gravitational wave and large scale structure observations
Antonio Enea Romano
We show that for Horndeski theories it is possible to derive mathematically compact consistency relations (CR) between physically observable quantities, valid for different classes…
Probing the dark Universe with gravitational waves
Antonio Enea Romano
Gravitational waves (GW) are expected to interact with dark energy and dark matter, affecting their propagation on cosmological scales. In order to model this interaction, we deriv…
The Effects of the Gravitational Coupling Variation on the Local Estimation
Antonio Enea Romano
We study the effects of the time evolution of the matter-gravity coupling on the luminosity distance, showing it can provide a natural explanation to the apparent Hubble tension. T…
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…
The Hitchhiker's guide to the galaxy catalog approach for gravitational wave cosmology
Jonathan R. Gair, Archisman Ghosh, Rachel Gray +28
We outline the ``dark siren'' galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in the implement…
