Extended FLRW Models: dynamical cancellation of cosmological anisotropies
Mikjel Thorsrud, Ben D. Normann, Thiago S. Pereira
We investigate a corner of the Bianchi models that has not received much attention: "extended FLRW models" (eFLRW) defined as a cosmological model with underlying anisotropic Bianc…
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 models with a free massless scalar field: invariant sets and higher symmetries
Mikjel Thorsrud
We scrutinize the overall structure of the space of cosmological models of Bianchi type I-VII that contain a free massless scalar field, with a spatially homogeneous gradient $…
Quintessence with Kaluza-Klein type couplings to matter and an isotropy-violating vector field
Mikjel Thorsrud
We study the dynamics of a scalar field with Kaluza-Klein type couplings to cold dark matter and an isotropy-violating vector field. The vector coupling, , has been stud…
Cosmologies in Horndeski's second-order vector-tensor theory
John D. Barrow, Mikjel Thorsrud, Kei Yamamoto
Horndeski derived a most general vector-tensor theory in which the vector field respects the gauge symmetry and the resulting dynamical equations are of second order. The action co…
