Abstract:
Type IIP supernovae (SNe) are recognized as independent extragalactic distance indicators; however, keeping in
mind the diverse nature of their observed properties as well as the availability of good quality data, more and
newer events need to be tested for their applicability as reliable distance indicators. We use early photometric
and spectroscopic data of eight Type IIP SNe to derive distances to their host galaxies by using the expanding
photosphere method (EPM). For five of these, the EPM is applied for the first time. In this work, we improved EPM
application by using SYNOW estimated velocities and by semi-deconvolving the broadband filter responses while
deriving color temperatures and blackbody angular radii. We find that the derived EPM distances are consistent
with that derived using other redshift-independent methods
