The angular clustering of infrared-selected obscured and unobscured quasars
DiPompeo, M. A.; Myers, A. D.; Hickox, R. C.; Geach, J. E.; Hainline, K. N. (2014-08-21)Recent studies of luminous infrared-selected active galactic nuclei (AGN) suggest that the reddest, most obscured objects display a higher angular clustering amplitude, and thus reside in higher mass darkmatter haloes. ... -
The Halo Mass of Optically Luminous Quasars at z ,F≈ ,F1-2 Measured via Gravitational Deflection of the Cosmic Microwave Background
Geach, J. E.; Peacock, J. A.; Myers, A. D.; Hickox, R. C.; Burchard, M. C.; Jones, M. L. (2019-03-27)We measure the average deflection of cosmic microwave background photons by quasars at 〈Z〉= 1.7. Our sample is selected from the Sloan Digital Sky Survey to cover the redshift range 0.9 ≤z≤2.2 with absolute i-band magnitudes ... -
The LABOCA Survey of the Extended Chandra Deep Field South : Clustering of submillimetre galaxies
Hickox, Ryan C.; Wardlow, J. L.; Smail, Ian; Myers, A. D.; Alexander, D. M.; Swinbank, A. M.; Danielson, A. L. R.; Stott, J. P.; Chapman, S.C.; Coppin, Kristen; Dunlop, J. S.; Gawiser, E.; Lutz, D.; van der Werf, P.; Weiss, A. (2012-03)We present a measurement of the spatial clustering of submillimetre galaxies (SMGs) at z = 1-3. Using data from the 870 micron LESS survey, we employ a novel technique to measure the cross-correlation between SMGs and ... -
Weighing obscured and unobscured quasar hosts with the cosmic microwave background
DiPompeo, M.A.; Myers, A. D.; Hickox, R. C.; Geach, James; Holder, G.; Hainline, K.N.; Hall, S.W. (2015-02)We cross-correlate a cosmic microwave background (CMB) lensing map with the projected space densities of quasars to measure the bias and halo masses of a quasar sample split into obscured and unobscured populations, the ...
