Redshift remapping and cosmic acceleration in dark-matter-dominated cosmological models
Radosław Wojtak, Francisco Prada
The standard relation between the cosmological redshift and cosmic scale factor underlies cosmological inference from virtually all kinds of cosmological observations, leading to t…

Voids in cosmological simulations over cosmic time
Radosław Wojtak, Devon Powell, Tom Abel
We study evolution of voids in cosmological simulations using a new method for tracing voids over cosmic time. The method is based on tracking watershed basins (contiguous regions…

Testing the mapping between redshift and cosmic scale factor
Radosław Wojtak, Francisco Prada
The canonical redshift-scale factor relation, 1/a=1+z, is a key element in the standard LambdaCDM model of the big bang cosmology. Despite its fundamental role, this relation has n…
