Kinematical Conformal Cosmology: Fundamental Parameters from Astrophysical Observations

Figure 3

Data from type Ia SNe “gold set” [48] are fitted with (52), our low-z approximation. Our fits show a remarkably good quality ( 𝜒 2 = 0 . 0 4 3 ; 𝑅 2 = 0 . 9 7 5 ) for both a variable 𝑎 (black dotted curve) and for fixed 𝑎 = 2 (solid blue curve). In this last case the best fit parameter for delta is 𝛿 0 = 3 . 8 3 6 × 1 0 5 . We also show (dashed green curves) the range of our fitting expressions for 𝛿 0 = 3 . 5 4 . 5 × 1 0 5 .
