Precise Time Delays from Strongly Gravitationally Lensed Type Ia Supernovae with Chromatically Microlensed Images
Daniel A. Goldstein, Peter E. Nugent, Daniel N. Kasen +1
Time delays between the multiple images of strongly lensed Type Ia supernovae (gl\sneia) have the potential to deliver precise cosmological constraints, but the effects of microlen…
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…
Automated Lensing Learner: Automated Strong Lensing Identification with a Computer Vision Technique
Camille Avestruz, Nan Li, Hanjue Zhu +3
Forthcoming surveys such as the Large Synoptic Survey Telescope (LSST) and Euclid necessitate automatic and efficient identification methods of strong lensing systems. We present a…
CMU DeepLens: Deep Learning For Automatic Image-based Galaxy-Galaxy Strong Lens Finding
Francois Lanusse, Quanbin Ma, Nan Li +5
Galaxy-scale strong gravitational lensing is not only a valuable probe of the dark matter distribution of massive galaxies, but can also provide valuable cosmological constraints,…
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…
H0LiCOW VII. Cosmic evolution of the correlation between black hole mass and host galaxy luminosity
Xuheng Ding, Tommaso Treu, Sherry H. Suyu +8
Strongly lensed active galactic nuclei (AGN) provide a unique opportunity to make progress in the study of the evolution of the correlation between the mass of supermassive black h…
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…
