Calibration of the Extragalactic Distance Scale
Abstract
Introduction to the lectures Cepheids Brief summary of the observed properties of cepheid variables Simple physical considerations Observational considerations Advances driven by new technology CCDs and multiwavelength coverage Obtaining accurate cepheid distances Local Group galaxies Beyond the Local Group The Hubble constant The future Contrasting aspects of the PL and PLC A reddening-free formulation of the PL relation Comments on reddening determinations Comparisons with other distance indicators The key project Other ground-based work Helium core flash and the tip of the red giant branch as a primary distance indicator The ideal distances indicator Some history concerning the red giant branch Concerns and technical issues An overview of the theoretical underpinnings: core helium ignition Recent applications of the TRGB method The scorecard Discussion Implications of the hipparcos observations of galactic cepheids Comparison with V-band period-luminosity relations Multiwavelength period-luminosity relations Discussion Implications of a cepheid distance to the Fornax cluster NGC 1365 and the Fornax cluster HST observations Cepheids in NGC 1365 The Hubble constant The Hubble constant at Fornax The nearby flow field Beyond Fornax: the Tully-Fisher relation Beyond Fornax: other relative distance determinations Beyond Fornax: type Ia supernovae Cosmological implications Conclusions References
