A study of inhomogeneous massless scalar gauge fields in cosmology
Ben David Normann, Sigbjørn Hervik, Angelo Ricciardone +1
Why is the Universe so homogeneous and isotropic? We summarize a general study of a -law perfect fluid alongside an inhomogeneous, massless scalar gauge field (with homogeneous…
Bianchi cosmologies with -form gauge fields
Ben David Normann, Sigbjørn Hervik, Angelo Ricciardone +1
In this paper the dynamics of free gauge fields in Bianchi type I-VII space-times is investigated. The general equations for a matter sector consisting of a -form field st…
Anisotropic cosmological solutions in gravity
Daniel Müller, Angelo Ricciardone, Alexei A. Starobinsky +1
In this paper we investigate the past evolution of an anisotropic Bianchi I universe in gravity. Using the dynamical system approach we show that there exists a new two-par…
Primordial Gravitational Waves with LISA
Angelo Ricciardone
Primordial Gravitational Waves are the next target of modern cosmology. They represent a window on the early Universe and the only probe of the physics and microphysics of the infl…
Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
