Redshift drift in an inhomogeneous universe: averaging and the backreaction conjecture
S. M. Koksbang, S. Hannestad
An expression for the average redshift drift in a statistically homogeneous and isotropic dust universe is given. The expression takes the same form as the expression for the redsh…

Studying the precision of ray tracing techniques with Szekeres models
S. M. Koksbang, S. Hannestad
The simplest standard ray tracing scheme employing the Born and Limber approximations and neglecting lens-lens coupling is used for computing the convergence along individual rays…

Methods for studying the accuracy of light propagation in N-body simulations
S. M. Koksbang, S. Hannestad
It is proposed to use exact, cosmologically relevant solutions to Einstein's equations to accurately quantify the precision of ray tracing techniques through Newtonian N-body simul…
