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…
Collins in Wonderland
Ben David Normann, Sigbjørn Hervik
What is the asymptotic future of a scalar-field model if the assumption of isotropy is relaxed in generic, homogeneous space-times with general relativity? This paper is a continua…
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…
Recursion relations for gravitational lensing
Ben David Normann, Chris Clarkson
The weak gravitational lensing formalism can be extended to the strong lensing regime by integrating a nonlinear version of the geodesic deviation equation. The resulting "roulette…
