The distances to five Type II supernovae using the expanding photosphere method, and the value of H[SUB]0[/SUB] Academic Article

abstract

• We have used observations gathered at CTIO to measure distances by the expanding photosphere method (EPM) to five Type II supernovae. These supernovae lie at redshifts from cz = 1100 km s-1 to cz = 5500 km s-1, and increase to 18 the number of distances measured using EPM. We compare distances derived to 11 Type II supernovae with distances to their host galaxies measured using the Tully-Fisher method. We find that the Tully-Fisher distances average 11% 7% smaller. The comparison shows no significant evidence of any large distance-dependent bias in the Tully-Fisher distances. We employ the sample of EPM distances from 4.5 Mpc to 180 Mpc to derive a value for the Hubble constant. We find H0 = 73 6(statistical) 7(systematic) km s-1 Mpc-1.
