Does replacing DESI DR2 BAO with DR1 change the preference for dynamical dark energy in DES-SN5YR and Union3, with Ωm = 0.315 ± 0.007?
The group exclusions produced unequal responses in the fit. The comparison established neither independence of the preference from every group nor exclusive dependence on any one group.
Does replacing DESI DR2 BAO with DR1 change the preference for dynamical dark energy in Pantheon+, DES-SN5YR and Union3, with Ωm = 0.33 ± 0.01 and BAO scale parameter = 30 ± 8?
The group exclusions produced unequal responses in the fit. The comparison established neither independence of the preference from every group nor exclusive dependence on any one group.
Does replacing DESI DR2 BAO with DR1 change the preference for dynamical dark energy in Pantheon+, DES-SN5YR and Union3, with Ωm = 0.33 ± 0.01 and BAO scale parameter = 30 ± 4?
The group exclusions produced unequal responses in the fit. The comparison established neither independence of the preference from every group nor exclusive dependence on any one group.
Does replacing DESI DR2 BAO with DR1 change the preference for dynamical dark energy in Pantheon+, DES-SN5YR and Union3, with Ωm = 0.315 ± 0.007 and BAO scale parameter = 30 ± 2?
The group exclusions produced unequal responses in the fit. The comparison established neither independence of the preference from every group nor exclusive dependence on any one group.
