Testing inhomogeneous cosmography in our cosmic neighborhood using CosmicFlows-4
S. M. Koksbang
The convergence of the third order general cosmographic expansion of the luminosity distance is examined using several versions of a semi-realistic model of our local cosmic neighb…
Backreaction in Numerical Relativity: Averaging on Newtonian gauge-like hypersurfaces in Einstein Toolkit cosmological simulations
Alexander Oestreicher, Sofie Marie Koksbang
We introduce a spatial averaging scheme and use it to study the evolution of spatial averages in large-scale simulations of cosmological structure formation performed with the Eins…
On the convergence of cosmographic expansions in Lemaitre-Tolman-Bondi models
Asha B. Modan, S. M. Koksbang
We study cosmographic expansions of the luminosity distance for a variety of Lemaitre-Tolman-Bondi models which we specify inspired by local large-scale structures of the universe.…
cp3-bench: A tool for benchmarking symbolic regression algorithms tested with cosmology
Mattias E. Thing, Sofie M. Koksbang
We introduce cp3-bench, a tool for comparing symbolic regression algorithms which we make publicly available at https://github.com/CP3-Origins/cp3-bench. Currently, cp3-bench inclu…
Redshift drift in a universe with structure III: Numerical relativity
Sofie Marie Koksbang, Asta Heinesen, Hayley J. Macpherson
Measurements of the cosmic redshift drift - the change in redshift of a source over time - will enable independent detection of cosmological expansion thanks to the immense precisi…
