The relative growth of Optical and Radio Quasars in SDSS
Francesco Shankar, Gregory R. Sivakoff, Marianne Vestergaard +1
We cross-correlate the SDSS DR3 quasar sample with FIRST and the Vestergaard et al. black hole (BH) mass sample to compare the mean accretion histories of optical and radio quasars…
On merger bias and the clustering of quasars
Silvia Bonoli, Francesco Shankar, Simon White +2
We use the large catalogues of haloes available for the Millennium Simulation to test whether recently merged haloes exhibit stronger large-scale clustering than other haloes of th…
Binary Quasars at High Redshift II: Sub-Mpc Clustering at z ~ 3-4
Yue Shen, Joseph F. Hennawi, Francesco Shankar +8
We present measurements of the small-scale (0.1<~ r <~ 1 Mpc/h) quasar two-point correlation function at z>2.9, for a flux-limited (i<21) sample of 15 binary quasars compiled by He…
Binary Quasars at High Redshift I: 24 New Quasar Pairs at z ~ 3-4
Joseph F. Hennawi, Adam D. Myers, Yue Shen +9
The clustering of quasars on small scales yields fundamental constraints on models of quasar evolution and the buildup of supermassive black holes. This paper describes the first s…
