The Extragalactic Distance Scale Key Project XVIII. The Discovery of Cepheids and a New Distance to NGC 4535 Using the Hubble Space Telescope
L. M. Macri, J. P. Huchra, P. B. Stetson +23
We report on the discovery of Cepheids in the Virgo spiral galaxy NGC 4535, based on observations made with the Wide Field and Planetary Camera 2 on board the Hubble Space Telescop…
The HST Key Project on the Extragalactic Distance Scale XIV. The Cepheids in NGC 1365
N. A. Silbermann, P. Harding, L. Ferrarese +21
We report the detection of Cepheid variable stars in the barred spiral galaxy NGC 1365, located in the Fornax cluster, using the Hubble Space Telescope Wide Field and Planetary Cam…
The HST Key Project on the Extragalactic Distance Scale XIII. The Metallicity Dependence of the Cepheid Distance Scale
R. Kennicutt, P. Stetson, A. Saha +22
Uncertainty in the metal abundance dependence of the Cepheid variable period- luminosity (PL) relation remains one of the outstanding sources of systematic error in the extragalact…
The Extragalactic Distance Scale Key Project VIII. The Discovery of Cepheids and a New Distance to NGC 3621 Using the Hubble Space Telescope
Daya M. Rawson, Lucas M. Macri, Jeremy R. Mould +18
We report on the discovery of Cepheids in the field spiral galaxy NGC 3621, based on observations made with the Wide Field and Planetary Camera 2 on board the Hubble Space Telescop…
Neural Networks and the Classification of Active Galactic Nucleus Spectra
Daya M. Rawson, Jeremy Bailey, Paul J. Francis
The use of Artificial Neural Networks (ANNs) as a classifier of digital spectra is investigated. Using both simulated and real data, it is shown that neural networks can be trained…
