We show that the dipole of the luminosity distance is a useful observational tool which allows us to determine the Hubble parameter as a function of the redshift H(z). We determine the number of supernovae needed to achieve a given precision for H(z) and to distinguish between different models for dark energy. We analyse a sample of nearby supernovae and find a dipole consistent with the cosmic microwave background at a significance of more than 2 sigma.

  1. New constraints on cosmic anisotropy from galaxy clusters using an improved dipole fitting method

    astro-ph.CO 2026-02 unverdicted novelty 5.0

    Galaxy cluster observations yield two preferred directions with cosmic anisotropy amplitude of about 5.3 times 10 to the minus 4 at roughly 1 sigma overall significance, though higher in the XMM-Newton subsample.
