Effective speed of gravitational waves
Antonio Enea Romano
We derive an effective equation and action for the propagation of gravitational waves (GW), encoding the effects of interaction and self-interaction in a time, frequency and polari…
Reconstructing homospectral inflationary potentials
Alexander Gallego Cadavid, Antonio Enea Romano, Andrew R. Liddle
Purely geometrical arguments show that there exist classes of homospectral inflationary cosmologies, i.e. different expansion histories producing the same spectrum of comoving curv…
tension or overestimation?
Brayan Yamid Del Valle Mazo, Antonio Enea Romano, Maryi Alejandra Carvajal Quintero
There is a strong discrepancy between the value of the Hubble parameter obtained from large scale observations such as the Planck mission, and the small scale value …
