Journal ArticleDOI
The Hubble Constant: A Summary of the HST Program for the Luminosity Calibration of Type Ia Supernovae by Means of Cepheids
TL;DR: In this paper, the authors present the fifth and final summary paper of the 15-year program using the Hubble Space Telescope (HST) to determine the Hubble constant using Type Ia supernovae, calibrated with Cepheid variables in nearby galaxies that hosted them.
Journal ArticleDOI
The Cepheid Distance to NGC 5236 (M 83) with the VLT
TL;DR: Karachentsev et al. as discussed by the authors adopted the true distance modulus to be (m-M)_0 = 28.25 +/- 0.15, which corresponds to a distance of 4.5 ± 0.3 Mpc.
Journal ArticleDOI
Cepheid Distances to SNe Ia Host Galaxies based on a Revised Photometric Zero-Point of the HST-WFPC2 and New P-L Relations and Metallicity Corrections
TL;DR: In this article, the authors examined the need for, and determined the value of, the corrections to the apparent magnitudes of our program Cepheids in the eleven previous calibration papers due to sensitivity drifts and charge transfer effects of the HST WFPC2 camera over the life time of the experiment from 1992 to 2001.
