Description
The Expanding Photosphere Method (EPM) determines distances to Type II supernova (SNe II) by comparing the photospheric angular size with the expansion velocity measured from spectral lines. The photospheres of SNe II are low density and are dominated by electron scattering, and consequently the photospheric flux is dilute relative to a Planck function at the best-fitting continuum color temperature. The reliability of EPM distances depends on understanding bow the dilution is related to...[Show more]
