Probe of spatial geometry from scalar induced gravitational waves
Utkarsh Kumar, Udaykrishna Thattarampilly, Pankaj Chaturvedi
We investigate a novel probe of spatial geometry of the Universe through the observation of gravitational waves (GWs) induced by first order curvature perturbations. The existence…

Gravitational-wave background in bouncing models from semi-classical, quantum and string gravity
Ido Ben-Dayan, Gianluca Calcagni, Maurizio Gasperini +4
We study the primordial spectra and the gravitational-wave background (GWB) of three models of semi-classical, quantum or string gravity where the big bang is replaced by a bounce…
