The HST Key Project on the Extragalactic Distance Scale. XV. A Cepheid Distance to the Fornax Cluster and Its Implications
Barry F. Madore, Wendy L. Freedman, N. Silbermann +13
Using the Hubble Space Telescope (HST) 37 long-period Cepheid variables have been discovered in the Fornax Cluster spiral galaxy NGC 1365. The resulting V and I period-luminosity r…
The HST Key Project on the Extragalactic Distance Scale XVII. The Cepheid Distance to NGC 4725
Brad K. Gibson, Shaun M. G. Hughes, Peter B. Stetson +22
The distance to NGC 4725 has been derived from Cepheid variables, as part of the Hubble Space Telescope Key Project on the Extragalactic Distance Scale. Thirteen F555W (V) and four…
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,…
The HST Key Project on the Extragalactic Distance Scale XII. The Discovery of Cepheids and a New Distance to NGC 2541
Laura Ferrarese, Fabio Bresolin, Robert C. Kennicutt +17
We report the detection of Cepheids and a new distance to the spiral galaxy NGC 2541, based on data obtained with the Wide Field and Planetary Camera 2 on board the Hubble Space Te…
On the Trend of [Mg/Fe] among Giant Elliptical Galaxies
F. Matteucci, R. Ponzone, B. K. Gibson
We revisit the problem of the flat slope of the Mg2 versus <Fe> relationship found for nuclei of elliptical galaxies (Faber et al. 1992; Worthey et al. 1992; Carollo et al. 1993; D…
The Hubble Space Telescope Extragalactic Distance Scale Key Project. X. The Cepheid Distance to NGC 7331
H0 Key Project, :, Shaun M. G. Hughes +19
The distance to NGC 7331 has been derived from Cepheid variables observed with HST/WFPC2, as part of the Extragalactic Distance Scale Key Project. Multi-epoch exposures in F555W (V…
