The Lema?tre-Hubble diagram in axial Bianchi IX universes with comoving dust

Axial Bianchi IX universes have compact, simply connected, homogeneous three-spaces and feature minimal symmetry breaking of the cosmological principle. We consider a positive cosmological constant, comoving dust and a mildly anisotropic expansion in the recent past, z < 6, which might be observable in the near future with the James Webb Space Telescope and the Vera Rubin Observatory. To this end we compute the direction dependent redshift and apparent luminosity of type 1a supernovae.To the memory of Vaughan Jones
