Models of gravitational lens candidates from Space Warps CFHTLS
Rafael Küng, Prasenjit Saha, Ignacio Ferreras +9
We report modelling follow-up of recently-discovered gravitational-lens candidates in the Canada France Hawaii Telescope Legacy Survey. Lens modelling was done by a small group of…
DES meets Gaia: discovery of strongly lensed quasars from a multiplet search
A. Agnello, H. Lin, N. Kuropatkin +69
We report the discovery, spectroscopic confirmation and first lens models of the first two, strongly lensed quasars from a combined search in WISE and Gaia over the DES footprint.…
The Hyper Suprime-Cam SSP Survey: Overview and Survey Design
H. Aihara, N. Arimoto, R. Armstrong +139
Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan…
Finding strong lenses in CFHTLS using convolutional neural networks
Colin Jacobs, Karl Glazebrook, Thomas Collett +2
We train and apply convolutional neural networks, a machine learning technique developed to learn from and classify image data, to Canada-France-Hawaii Telescope Legacy Survey (CFH…
Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). I. Automatic search for galaxy-scale strong lenses
Alessandro Sonnenfeld, James H. H. Chan, Yiping Shu +12
The Hyper Suprime-Cam Subaru Strategic Program (HSC SSP) is an excellent survey for the search for strong lenses, thanks to its area, image quality and depth. We use three differen…
Core or cusps: The central dark matter profile of a redshift one strong lensing cluster with a bright central image
Thomas E. Collett, Elizabeth Buckley-Geer, Huan Lin +58
We report on SPT-CLJ2011-5228, a giant system of arcs created by a cluster at . The arc system is notable for the presence of a bright central image. The source is a Lyman…
