Robustness of H0 determination at intermediate redshifts
The most recent Hubble constant (H0) estimates from local methods (z << 1), H0 = 73.8±2.4 km s 1 Mpc 1 , and the one from high redshits (Planck Collaboration 2013), H0 = 67.3 ± 1.2 km s 1 Mpc 1 , are discrepant at 2.4σ confidence level. Within this context, Lima & Cunha (LC) (ApJL 781, 38, 2014) derived a new determination of H0 using four cosmic probes at intermediate redshifts (0.1 < z < 1.8) based on the
