Modeling Uncertainties in Modified Gravity Predictions for the Stochastic Gravitational-Wave Background
Rodrigo Fraga, Rafael C. Nunes
We investigate the impact of modified gravity on the stochastic gravitational-wave background (SGWB) generated by a cosmological population of unresolved binary black hole mergers.…

Cosmic inflation in an extended non-commutative foliated quantum gravity: the wave function of the universe
César A. Zen Vasconcellos, Peter O. Hess, José de Freitas Pacheco +8
We propose a novel extension to the recently developed non-commutative Riemannian foliated branch-cut quantum gravity (BCQG). Based on an extended Faddeev-Jackiw symplectic deforma…
