On the Hubble Constant Tension in the SNe Ia Pantheon Sample
The Hubble constant ($H_0$) tension between Type Ia Supernovae (SNe Ia) and Planck measurements ranges from 4 to 6 $\sigma$. To investigate this tension, we estimate $H_0$ in the $\Lambda$CDM and $w_0w_a$CDM models by dividing the Pantheon sample, the largest compilation of SNe Ia, into 3, 4, 20 and 40 bins.
