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…
First investigation of void statistics in numerical relativity simulations
Michael J. Williams, Hayley J. Macpherson, David L. Wiltshire +1
We apply and extend standard tools for void statistics to cosmological simulations that solve Einstein's equations with numerical relativity (NR). We obtain a simulated void catalo…
The impact of anisotropic sky-sampling on the Hubble constant in numerical relativity
Hayley J. Macpherson
We study the impact of nearby inhomogeneities on an observer's inference of the Hubble constant. Large-scale structures induce a dependence of cosmological parameters on observer p…
Towards Cosmography of the Local Universe
Julian Adamek, Chris Clarkson, Ruth Durrer +3
Anisotropies in the distance-redshift relation of cosmological sources are expected due to large-scale inhomogeneities in the local Universe. When the observed sources are tracing…
