Cosmological density versus velocity-divergence relation in the Zel'dovich approximation
Michal Chodorowski
I derive a relation, both `forward' and `inverse', between the density and the divergence of the peculiar velocity which results from the Zel'dovich approximation. My calculations…

Large-Scale Density--Velocity Relations
Michal Chodorowski
I present recent progress in theoretical modelling of cosmological density--velocity relations in the weakly nonlinear regime. The relations are local, based on rigorous perturbati…
