Figure 2From: The luminosity-redshift relation in brane-worlds: II. Confrontation with experimental data(Color online) The luminosity distance – redshift relation for the viable brane-world models and the ΛCDM model (the curves (1)–(4) of Fig 1), both with logarithmic (left panel) and linear scale (right panel), compared to the smeared Gold set [23]. The best fit is obtained for the brane-world model (3), with 5% dark radiation.Back to article page
