Topic Maps as a Virtual Observatory tool
A. Mahabal, S. G. Djorgovski, R. Brunner +1
One major component of the VO will be catalogs measuring gigabytes and terrabytes if not more. Some mechanism like XML will be used for structuring the information. However, such m…
Composite Quasar Spectra From the Sloan Digital Sky Survey
SDSS Collaboration, Daniel E. Vanden Berk
We have created a variety of composite quasar spectra using a homogeneous data set of over 2200 spectra from the Sloan Digital Sky Survey (SDSS). The quasar sample spans a redshift…
Exploration of Large Digital Sky Surveys
S. G. Djorgovski, R. J. Brunner, A. A. Mahabal +8
We review some of the scientific opportunities and technical challenges posed by the exploration of the large digital sky surveys, in the context of a Virtual Observatory (VO). The…
A Probabilistic Quantification of Galaxy Cluster Membership
R. J. Brunner, L. M. Lubin
Clusters of galaxies are important laboratories for understanding both galaxy evolution and constraining cosmological quantities. Any analysis of clusters, however, is best done wh…
Simulated Extragalactic Observations with a Cryogenic Imaging Spectrophotometer
Ben A. Mazin, Robert J. Brunner
In this paper we explore the application of cryogenic imaging spectrophotometers. Prototypes of this new class of detector, such as superconducting tunnel junctions (STJs) and tran…
Photometric Redshifts: A New Tool for Studying High-Redshift Clusters
L. M. Lubin, R. J. Brunner
We present the first results of our application of photometric redshifts to the study of galaxy populations in high-redshift clusters. For this survey, we are examining a sample of…
