The Cepheid distance to M96 and the Hubble constant.

TANVIR N.R., FERGUSON H.C. and SHANKS T.

Abstract (from CDS):

HST WFPC2 observations of Cepheids in M96 (NGC 3368) are used to find a distance to that galaxy of 11.2±1.0Mpc. This estimate is based on a calibration of the Cepheid period-luminosity relation in the Large Magellanic Cloud, and includes a correction for the difference in metallicity between the two systems. There are good reasons for believing M96 is at the same distance as four E/S0 galaxies in the Leo-I group, and hence we calibrate secondary distance indicators based on the early-type galaxies, namely the fundamental plane and surface-brightness-fluctuation method. Also the Type Ia supernova 1998bu occurred in M96 itself and is used to calibrate the SN Ia distance scale. These methods reach to recession velocities of greater than 5000km.s–1 and can therefore allow us to evaluate the Hubble constant without reference to the peculiar velocity of M96 itself. In fact, these indicators agree well between themselves and hence we find H0=67±7km.s–1.Mpc–1 where the quoted error includes estimates of potential systematic effects.
