Abstract

The mismatch between different independent measurements of the expansion rate of the Universe is known as the Hubble constant (H₀) tension, and it is a serious and pressing problem in cosmology. We investigate this tension considering the dataset from the Pantheon sample, a collection of 1048 Type Ia Supernovae (SNe Ia) with a redshift range 0
