Axial Bianchi IX meets Gaia data
Thomas Schücker
The aim of the present work is two-fold: {\it(i)} Compute the drift of comoving extragalactic sources in axial Bianchi IX universes, in particular in those satisfying Einstein's eq…

Axial Bianchi I meets drifting extragalactic sources
Thomas Schücker
We recompute {\it ab initio} the drift of comoving sources in axial Bianchi I universes. Our result resolves the long-standing disagreement between the computations by Quercellini…
