 Gravitoelectromagnetic quadrirefringence and the binaries rainbow / Romano, Antonio Enea (King's Coll. London ; CERN ; ICRA, Pescara) ; Vallejo-Peña, Sergio A. (ICRA, Pescara) The interaction between gravitational waves (GW) and electromagnetic waves (EMW) produces quadrirefringence, a phenomenon consisting in a frequency and polarization dependency of the speed of GW and EMW.

 A unified effective approach to cosmological perturbations / Romano, Antonio Enea (ICRA, Pescara) A unified model independent effective description of cosmological perturbations is derived in terms of two effective quantities, playing the role of effective propagation speeds of curvature perturbations and gravitational waves, encoding the effects of the interaction of perturbations at any order, and inducing a modification of the friction term of the perturbations propagation equation.
