  Type Ia Supernovae (SNe Ia) are used as reliable cosmic distance indicators
and their standardization is necessary for a more accurate measurement of the
cosmological parameters of the Universe. However, the Hubble diagram still
shows some intrinsic dispersion, potentially influenced by the supernova's
environment. In this study, we reproduce the Hubble diagram fit for the
Pantheon supernova sample, and also investigate the possibility of introducing
various standardization equations for supernovae exploded in early- and
late-type galaxies. We analyze 330 Pantheon SNe Ia to study how host galaxy
morphology affects their standardization. We find that SNe Ia hosted by
early-type galaxies have different standardization parameters compared to those
hosted by late-type galaxies. We conclude that correcting supernova luminosity
for host galaxy morphology is essential to perform the precise cosmological
analysis.
