Distance Determination To Eight Galaxies Using Expanding Photosphere
  Method
  Type IIP supernovae are recognized as independent extragalactic distance
indicators, however, keeping in view of 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 a reliable distance
indicators. We use early photometric and spectroscopic data of eight type-IIP
SNe to derive distances to their host galaxies using the expanding photosphere
method (EPM). For five of these, 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 black-body angular radii. We find that the derived EPM
distances are consistent with that derived using other redshift independent
methods.
