A short review on joint weak and strong cluster lens-mass reconstruction
Ben David Normann, Kenny Solevåg-Hoti, Hans Georg Schaathun
The distinction between weak and strong lensing is somewhat arbitrary, and both regimes are manifestations of the same physical phenomenon: gravity bending the path of light. Never…
On the simulation of gravitational lensing
Hans Georg Schaatun, Ben David Normann, Einar Leite Austnes +3
Gravitational lensing refers to the deflection of light by the gravity of celestial bodies, often predominantly composed of dark matter. Seen through a gravitational lens, the imag…
Can the Hubble tension be resolved by bulk viscosity?
Ben David Normann, Iver Håkon Brevik
We show that the cosmic bulk viscosity estimated in our previous works is sufficient to bridge the value inferred from observations of the early universe with the value infer…
Remarks on cosmological bulk viscosity in different epochs
Iver Brevik, Ben David Normann
The intention of this paper is mainly two-fold. \textit{First}, we point out a striking numerical agreement between the bulk viscosity in the lepton era calculated by Husdal (2016)…
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…
