The dipole of the luminosity distance: a direct measure of H(z)
journal contribution
posted on 2023-06-07, 20:36 authored by Camile Bonvin, Ruth Durrer, Martin KunzWe 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 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 analyze a sample of nearby supernovae and find a dipole consistent with the cosmic microwave background at a significance of more than 2sigma.

Notes
Shows how the dipole of the angular distribution of supernovae measures the Hubble parameter as function of redshift, and that the low-z dipole is consistent with the CMB one. The result follows from an earlier paper by Bonvin and Durrer, I did the numerical analysis for this paper. (16 HEP/SPIRES citations)Full text available
