    Abstract

    In this paper, we propose a self-consistent test for a Hubble constant estimate using galaxy cluster and type Ia supernovae (SNe Ia) observations. The approach consists, in a first step, of obtaining the observational value of the galaxy cluster scaling-relation YSZEDA2/CXSZYX=C by combining the X-Ray and SZ observations of galaxy clusters at low redshifts (z 0.1. As a result, we obtain H0=73.014-6.688+7.435 km/s/Mpc, in full agreement with the latest results from HST + SH0ES team. We also compare our method with that one where the C parameter is obtained from hydrodynamical simulations of massive galaxy clusters
