The 2dF-SDSS LRG and QSO Survey: QSO clustering and the L-z degeneracy
J. da Angela, T. Shanks, S. M. Croom +12
We combine the QSO samples from the 2dF QSO Redshift Survey (2QZ) and the 2dF-SDSS LRG and QSO Survey (2SLAQ) in order to investigate the clustering of z~1.4 QSOs and measure the c…
Clustering Analyses of 300,000 Photometrically Classified Quasars--II. The Excess on Very Small Scales
Adam D. Myers, Robert J. Brunner, Gordon T. Richards +3
We study quasar clustering on small scales, modeling clustering amplitudes using halo-driven dark matter descriptions. From 91 pairs on scales <35 kpc/h, we detect only a slight ex…
Clustering Analyses of 300,000 Photometrically Classified Quasars--I. Luminosity and Redshift Evolution in Quasar Bias
Adam D. Myers, Robert J. Brunner, Robert C. Nichol +3
Using ~300,000 photometrically classified quasars, by far the largest quasar sample ever used for such analyses, we study the redshift and luminosity evolution of quasar clustering…
Buoyant Bubbles in a Cooling Intracluster Medium I. Hydrodynamic Bubbles
A. Gardini
Over the past several years, numerous examples of X-ray cavities coincident with radio sources have been observed in so-called "cool core" clusters of galaxies. Motivated by these…
The Co-Formation of Spheroids and Quasars Traced in their Clustering
Philip F. Hopkins, Adam Lidz, Lars Hernquist +4
We compare observed clustering of quasars and galaxies as a function of redshift, mass, luminosity, & color/morphology, to constrain models of quasar fueling and spheroid-BH co-evo…
Broad Absorption Line Variability in Repeat Quasar Observations from the Sloan Digital Sky Survey
Britt F. Lundgren, Brian C. Wilhite, Robert J. Brunner +5
We present a time-variability analysis of 29 broad absorption line quasars (BALQSOs) observed in two epochs by the Sloan Digital Sky Survey (SDSS). These spectra are selected from…
