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:…

A catalogue of white dwarf candidates in VST ATLAS

Nicola Pietro Gentile Fusillo, Roberto Raddi, Boris T. Gänsicke +6

The Sloan Digital Sky Survey (SDSS) has created a knowledge gap between the Northern and the Southern hemispheres which is very marked for white dwarfs: only % of the kn…

First lensed quasar systems from the VST-ATLAS survey: one quad, two doubles and two pairs of lensless twins

Paul L. Schechter, Nicholas D. Morgan, B. Chehade +3

We have analyzed images from the VST ATLAS survey to identify candidate gravitationally lensed quasar systems in a sample of WISE sources with W1 - W2 > 0.7. Results from followup…

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…
