Is every strong lens model unhappy in its own way? Uniform modelling of a sample of 13 quadruply+ imaged quasars
A. J. Shajib, S. Birrer, T. Treu +70
Strong-gravitational lens systems with quadruply-imaged quasars (quads) are unique probes to address several fundamental problems in cosmology and astrophysics. Although they are i…
The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2016 follow-up campaign. II. New quasar lenses from double component fitting
T. Anguita, P. L. Schechter, N. Kuropatkin +56
We report upon the follow up of 34 candidate lensed quasars found in the Dark Energy Survey using NTT-EFOSC, Magellan-IMACS, KECK-ESI and SOAR-SAMI. These candidates were selected…
Gravitationally Lensed Quasars in Gaia: II. Discovery of 24 Lensed Quasars
Cameron A. Lemon, Matthew W. Auger, Richard G. McMahon +1
We report the discovery, spectroscopic confirmation and preliminary characterisation of 24 gravitationally lensed quasars identified using Gaia observations. Candidates were select…
The Discovery of a Five-Image Lensed Quasar at z = 3.34 using PanSTARRS1 and Gaia
Fernanda Ostrovski, Cameron A. Lemon, Matthew W. Auger +8
We report the discovery, spectroscopic confirmation, and mass modelling of the gravitationally lensed quasar system PS J0630-1201. The lens was discovered by matching a photometric…
OzDES multifibre spectroscopy for the Dark Energy Survey: Three year results and first data release
M. J. Childress, C. Lidman, T. M. Davis +98
We present results for the first three years of OzDES, a six-year programme to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre pos…
Models of the strongly lensed quasar DES J0408-5354
Adriano Agnello, Huan Lin, L. Buckley-Geer +82
We present gravitational lens models of the multiply imaged quasar DES J0408-5354, recently discovered in the Dark Energy Survey (DES) footprint, with the aim of interpreting its r…
Discovery of the Lensed Quasar System DES J0408-5354
H. Lin, E. Buckley-Geer, A. Agnello +78
We report the discovery and spectroscopic confirmation of the quad-like lensed quasar system DES J0408-5354 found in the Dark Energy Survey (DES) Year 1 (Y1) data. This system was…
Eight new luminous z > 6 quasars selected via SED model fitting of VISTA, WISE and Dark Energy Survey Year 1 Observations
S. L. Reed, R. G. McMahon, P. Martini +60
We present the discovery and spectroscopic confirmation with the ESO NTT and Gemini South telescopes of eight new 6.0 < z < 6.5 quasars with z < 21.0. These quasars were pho…
A Study of Quasar Selection in the Dark Energy Survey Supernova fields
S. S. Tie, P. Martini, D. Mudd +75
We present a study of quasar selection using the DES supernova fields. We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completenes…
VDES J2325-5229 a z=2.7 gravitationally lensed quasar discovered using morphology independent supervised machine learning
Fernanda Ostrovski, Richard G. McMahon, Andrew J. Connolly +56
We present the discovery and preliminary characterization of a gravitationally lensed quasar with a source redshift and image separation of lensed by a foregrou…
The Dark Energy Survey: more than dark energy - an overview
Dark Energy Survey Collaboration, T. Abbott, F. B. Abdalla +138
This overview article describes the legacy prospect and discovery potential of the Dark Energy Survey (DES) beyond cosmological studies, illustrating it with examples from the DES…
Discovery of two gravitationally lensed quasars in the Dark Energy Survey
Adriano Agnello, Tommaso Treu, Fernanda Ostrovski +77
We present spectroscopic confirmation of two new lensed quasars via data obtained at the 6.5m Magellan/Baade Telescope. The lens candidates have been selected from the Dark Energy…
