TDCOSMO. VII. Boxyness/discyness in lensing galaxies : Detectability and impact on
Lyne Van de Vyvere, Matthew R. Gomer, Dominique Sluse +4
In the context of gravitational lensing, the density profile of lensing galaxies is often considered to be perfectly elliptical. Potential angular structures are generally ignored,…
Discovery of Strongly Lensed Quasars in the Ultraviolet Near Infrared Optical Northern Survey (UNIONS)
J. H. H. Chan, C. Lemon, F. Courbin +13
We report the discovery of five new doubly-imaged lensed quasars from the first 2500 square degrees of the ongoing Canada-France Imaging Survey (CFIS), which is a component of the…
SEAGLE--III: Towards resolving the mismatch in the dark-matter fraction in early-type galaxies between simulations and observations
Sampath Mukherjee, Léon V. E. Koopmans, Crescenzo Tortora +4
The central dark-matter fraction of galaxies is sensitive to feedback processes during galaxy formation. Strong gravitational lensing has been effective in the precise measurement…
Strong lensing in UNIONS: Toward a pipeline from discovery to modeling
E. Savary, K. Rojas, M. Maus +16
We present a search for galaxy-scale strong gravitational lenses in the initial 2 500 square degrees of the Canada-France Imaging Survey (CFIS). We designed a convolutional neural…
High-quality strong lens candidates in the final Kilo Degree survey footprint
R. Li, N. R. Napolitano, C. Spiniello +16
We present 97 new high-quality strong lensing candidates found in the final , that completed the full area of the Kilo-Degree Survey (Ki…
Strong lens systems search in the Dark Energy Survey using Convolutional Neural Networks
K. Rojas, E. Savary, B. Clément +8
We performed a search for strong lens galaxy-scale systems in the first data release of the Dark Energy Survey (DES), from a color-selected parent sample of 18~745~029 Luminous Red…
Simulating time-varying strong lenses
Georgios Vernardos
We present a self-consistent and versatile forward modelling software package that can produce time series and pixel-level simulations of time-varying strongly lensed systems. The…
