The Baryon Oscillation Spectroscopic Survey of SDSS-III
Kyle S. Dawson, David J. Schlegel, Christopher P. Ahn +162
The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger volume than the…
PHL 1811 Analogs: A Population of X-ray Weak Quasars
Jianfeng Wu, W. N. Brandt, Patrick B. Hall +6
We report on a population of X-ray weak quasars with similar UV emission-line properties to those of the remarkable quasar PHL 1811. All radio-quiet PHL 1811 analogs are notably X-…
A Population of X-ray Weak Quasars: PHL 1811 Analogs at High Redshift
Jianfeng Wu, W. N. Brandt, Patrick B. Hall +6
We report the results from Chandra and XMM-Newton observations of a sample of 10 type 1 quasars selected to have unusual UV emission-line properties (weak and blueshifted high-ioni…
