Quantifying effects of inhomogeneities and curvature on gravitational wave standard siren measurements of
S. M. Koksbang
For a flat CDM universe, the dipole of the luminosity distance can be utilized to measure the Hubble parameter. It is here shown that this is not the case in more general settin…
Understanding the Dyer-Roeder approximation as a consequence of local cancellations of projected shear and expansion rate fluctuations
S. M. Koksbang
It is shown with several concrete examples that the Dyer-Roeder approximation is valid in spacetimes which fulfill the condition that fluctuations in the expansion rate along a lig…
Searching for signals of inhomogeneity using multiple probes of the cosmic expansion rate H(z)
S. M. Koksbang
It is argued that cosmic chronometers yield estimates of the spatially averaged expansion rate even in a universe that is not well described by a global FLRW model - as long as the…
On the relationship between mean observations, spatial averages and the Dyer-Roeder approximation in Einstein-Straus models
S. M. Koksbang
The redshift and redshift-distance relation in different Einstein-Straus models are considered. Specifically, the mean of these observables along 1000 light rays in different speci…
Light path averages in spacetimes with non-vanishing average spatial curvature
S. M. Koksbang
Effects of inhomogeneities on observations have been vastly studied using both perturbative methods, N-body simulations and Swiss cheese solutions to the Einstein equations. In nea…
Towards statistically homogeneous and isotropic perfect fluid universes with cosmic backreaction
S. M. Koksbang
A method for constructing statistically homogeneous and isotropic perfect fluid universe models with significant cosmic backreaction is proposed. The method is illustrated using a…
