On the viability of bigravity cosmology
Michael Kenna-Allison, A. Emir Gumrukcuoglu, Kazuya Koyama
We revisit the question of viability of bigravity cosmology as a candidate for dark energy. In the context of the low energy limit model, where matter couples to a single metric, w…
Phenomenology of Large Scale Structure in scalar-tensor theories: joint prior covariance of , and in Horndeski
Juan Espejo, Simone Peirone, Marco Raveri +3
Ongoing and upcoming cosmological surveys will significantly improve our ability to probe the equation of state of dark energy, , and the phenomenology of Large Scale S…
A new approach to cosmological structure formation with massive neutrinos
Christian Fidler, Alexander Kleinjohann, Thomas Tram +2
We show how Newtonian cosmological simulations can be employed to investigate the non-linear evolution of two particle species in a relativistic context. We discuss the application…
Non-Gaussianity from Axion-Gauge Fields Interactions during Inflation
Emanuela Dimastrogiovanni, Matteo Fasiello, Robert J. Hardwick +3
We study the scalar-tensor-tensor non-Gaussian signal in an inflationary model comprising also an axion coupled with SU(2) gauge fields. In this set-up, metric fluctuations are sou…
A precise extragalactic test of General Relativity
Thomas E. Collett, Lindsay J. Oldham, Russell J. Smith +7
Einstein's theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby str…
Color-gradient lattice Boltzmann model with nonorthogonal central moments: Hydrodynamic melt-jet breakup simulations
Shimpei Saito, Alessandro De Rosis, Alessio Festuccia +3
We develop a lattice Boltzmann (LB) model for immiscible two-phase flow simulations with central moments (CMs). This successfully combines a three-dimensional nonorthogonal CM-base…
