RR Lyrae Stars and Anomalous Cepheids in the Draco Dwarf Spheroidal Galaxy
K. Kinemuchi, H. A. Smith, A. LaCluyze +4
We present new results on RR Lyrae stars and anomalous Cepheids in the Draco dwarf spheroidal galaxy. We have increased the number of double-mode RR Lyrae stars and found three new…
Type Ia Supernovae and the Value of the Hubble Constant
Brad K. Gibson, Chris B. Brook
The methodology involved in deriving the Hubble Constant via the calibration of the corrected peak luminosities of Type Ia supernovae (SNe) is reviewed. We first present a re-analy…
The Hubble Constant from the HST Key Project on the Extragalactic Distance Scale
Laura Ferrarese, Brad Gibson, Daniel Kelson +14
The final efforts of the HST Key Project on the Extragalactic Distance Scale are presented. Four distance indicators, the Surface Brightness Fluctuation method, the Fundamental Pla…
A Cepheid Distance to the Fornax Cluster
B. F. Madore, W. L. Freedman, N. Silbermann +13
The Hubble Space Telescope is being used to measure accurate Cepheid distances to nearby galaxies with the ultimate aim of determining the Hubble constant, H_0. For the first time,…
ISO measurements of [CII] line variations in galaxies
S. Malhotra, G. Helou, G. Stacey +11
We report measurements of the [CII] fine structure line at 157.714 micron in 30 normal star-forming galaxies with the Long Wavelength Spectrometer (LWS) on the Infrared Space Obser…
