Star Formation and Substructure in Galaxy Clusters
Seth A. Cohen, Ryan C. Hickox, Gary A. Wegner +2
We investigate the relationship between star formation (SF) and substructure in a sample of 107 nearby galaxy clusters using data from the Sloan Digital Sky Survey (SDSS). Several…
Tracing the evolution of Active Galactic Nuclei host galaxies over the last 9 Gyrs of Cosmic time
Andy D. Goulding, William R. Forman, Ryan C. Hickox +11
We present the results of a combined galaxy population analysis for the host galaxies of active galactic nuclei (AGN) identified at 0 < z < 1.4 within the SDSS, Bootes and DEEP2 su…
SALT Long-slit Spectroscopy of Luminous Obscured Quasars: An Upper Limit on the Size of the Narrow-Line Region?
Kevin N. Hainline, Ryan C. Hickox, Jenny E. Greene +2
We present spatially resolved long-slit spectroscopy from the Southern African Large Telescope (SALT) to examine the spatial extent of the narrow-line regions (NLRs) of a sample of…
A direct measurement of the linear bias of mid-infrared-selected quasars at z~1 using cosmic microwave background lensing
J. E. Geach, R. C. Hickox, L. E. Bleem +52
We measure the cross-power spectrum of the projected mass density as traced by the convergence of the cosmic microwave background lensing field from the South Pole Telescope (SPT)…
Weak Hard X-ray Emission from Two Broad Absorption Line Quasars Observed with NuSTAR: Compton-thick Absorption or Intrinsic X-ray Weakness?
B. Luo, W. N. Brandt, D. M. Alexander +22
We present NuSTAR hard X-ray observations of two X-ray weak broad absorption line (BAL) quasars, PG 1004+130 (radio loud) and PG 1700+518 (radio quiet). Many BAL quasars appear X-r…
A correlation between star formation rate and average black hole accretion in star forming galaxies
Chien-Ting J. Chen, Ryan C. Hickox, Stacey Alberts +14
We present a measurement of the average supermassive black hole accretion rate (BHAR) as a function of star formation rate (SFR) for galaxies in the redshift range 0.25<z<0.8. We s…
