Quasars probing quasars X: The quasar pair spectral database
Joseph R. Findlay, J. Xavier Prochaska, Joseph F. Hennawi +8
The rare close projection of two quasars on the sky provides the opportunity to study the host galaxy environment of a foreground quasar in absorption against the continuum emissio…
Two more, bright, z > 6 quasars from VST ATLAS and WISE
B. Chehade, A. C. Carnall, T. Shanks +10
Recently, Carnall et al. discovered two bright high redshift quasars using the combination of the VST ATLAS and WISE surveys. The technique involved using the 3-D colour plane i-z:…
The 2QDES Pilot : The luminosity and redshift dependence of quasar clustering
Ben Chehade, T. Shanks, J. Findlay +10
We present a new redshift survey, the 2dF Quasar Dark Energy Survey pilot (2QDESp), which consists of quasars from deg of the southern sky, base…
The VLT Survey Telescope ATLAS
T. Shanks, N. Metcalfe, B. Chehade +9
The VLT Survey Telescope (VST) ATLAS is an optical ugriz survey aiming to cover ~4700deg^2 of the Southern sky to similar depths as the Sloan Digital Sky Survey (SDSS). From reduce…
Two bright z > 6 quasars from VST ATLAS and a new method of optical plus mid-infra-red colour selection
A. C. Carnall, T. Shanks, B. Chehade +6
We present the discovery of two z > 6 quasars, selected as i band dropouts in the VST ATLAS survey. Our first quasar has redshift, z = 6.31 \pm 0.03, z band magnitude, z_AB = 19.63…
