How the Hubble flow in an anisotropic Universe looks like?

Abstract

Using formulae for light propagation, redshift and photometric distance in a Bianchi I anisotropic Universe, we create a picture of the Hubble flow that could be observed by a hypothetical observer in the anisotropic Universe. The algorithm used can be applied (after some modification) for more complicated visualizations of a sky seen by an observer in strong gravitational fields.
