Grist: Grid-based Data Mining for Astronomy
Joseph C. Jacob, Roy Williams, Jogesh Babu +8
The Grist project (http://grist.caltech.edu/) is developing a grid-technology based system as a research environment for astronomy with massive and complex datasets. This knowledge…
Eigenspectra of the SDSS DR1 quasars
Ching-Wa Yip, Andrew Connolly, Daniel Vanden Berk +4
We construct eigenspectra from the DR1 quasars in the SDSS using the Karhunen-Loève (KL) transform (or Principal Component Analysis, PCA) in different redshift and luminosity bins.…
Constraints on Quasar Continuum, BELR, and BALR Physics from SDSS Composite Spectra
Gordon T. Richards, Patrick B. Hall, Timothy A. Reichard +3
We review recent results on quasars from the SDSS as they relate to our understanding of the UV/optical continuum, the broad emission line region, and the broad absorption line reg…
Luminosity and Redshift Dependence of Quasar Spectral Properties
D. E. Vanden Berk, C. -Y. Yip, A. J. Connolly +2
Using a large sample of quasar spectra from the SDSS, we examine the composite spectral trends of quasars as functions of both redshift and luminosity, independently of one another…
Extreme BAL Quasars from the Sloan Digital Sky Survey
Patrick B. Hall, J. E. Gunn, G. R. Knapp +16
The Sloan Digital Sky Survey has discovered a population of broad absorption line quasars with various extreme properties. Many show absorption from metastable states of FeII with…
