Calculating the distance to SN 2007gr using the Expanding Photosphere Method

POSTER

Abstract

SN 2007gr is a type Ic supernova observed extensively by the Robotic Optical Transient Search Experiment (ROTSE). While the expanding photosphere method (EPM) is typically used to measure the distance to type IIP supernovae, this analysis aims to apply EPM to SN 2007gr. Although this object does not possess the hydrogen and helium envelope that is typically required for EPM, this work aims to assess the accuracy of this method of obtaining accurate cosmological distance measurements using a stripped envelope supernova.
