摘要: Recently released Planck data favor a lower value of the Hubble constant and a higher value of the fraction matter density in the standard ΛCDM model, which are discrepant with some of the low-redshift measurements. Within the context of this cosmology, we examine the consistency of the estimated values for the Hubble constant and fraction matter density with redshift tomography. Using the SNe Ia, Hubble parameter, BAO and reduced CMB data, which are divided into three bins, we find no statistical evidence for any tension in the three redshift bins.
