Gravitational waves from two scalar fields unifying the dark sector with inflation
Orlando Luongo, Tommaso Mengoni, Paulo M. Sá
We investigate the gravitational-wave background predicted by a two-scalar-field cosmological model that aims to unify primordial inflation with the dark sector, namely late-time d…
