Discovery of a High-Redshift (z=0.96) Cluster of Galaxies Using a FIRST Wide-Angle Tailed Radio Source
Elizabeth L. Blanton, Michael D. Gregg, David J. Helfand +2
Using a combination of near-infrared and optical photometry, along with multi-object spectroscopy, we have confirmed the existence of a high-redshift cluster of galxies at z = 0.96…
A Young Blue Tidal Stream in NGC 5128
Eric W. Peng, Holland C. Ford, Kenneth C. Freeman +1
Stellar streams in galaxy halos are the natural consequence of a history of merging and accretion. We present evidence for a blue tidal stream of young stars in the nearest giant e…
FIRST J102347.6+003841: The First Radio-Selected Cataclysmic Variable
Howard E. Bond, Richard L. White, Robert H. Becker +1
We have identified the 1.4 GHz radio source FIRST J102347.6+003841 (hereafter FIRST J1023+0038) with a previously unknown 17th-mag Galactic cataclysmic variable (CV). The optical s…
An FeLoBAL Binary Quasar
Michael D. Gregg, Robert H. Becker, Richard L. White +3
In an ongoing infrared imaging survey of quasars at Keck Observatory, we have discovered that the z=1.285 quasar SDSS J233646.2-010732.6 comprises two point sources with a separati…
Unusual Broad Absorption Line Quasars from the Sloan Digital Sky Survey
Patrick B. Hall, S. F. Anderson, M. A. Strauss +6
The Sloan Digital Sky Survey has confirmed the existence of populations of broad absorption line (BAL) quasars with various unusual properties. We present and discuss twenty-three…
The Reddest Quasars II. A gravitationally-lensed FeLoBAL quasar
M. Lacy, M. Gregg, R. H. Becker +4
We report the discovery of a z=2.65 low-ionization iron broad absorption line quasar, FIRST J100424.9+122922, which is gravitationally-lensed by a galaxy at z~0.95. The object was…
