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…
Constraining quasar structure using high-frequency microlensing variations and continuum reverberation
E. Paic, G. Vernardos, D. Sluse +4
Gravitational microlensing is a powerful tool to probe the inner structure of strongly lensed quasars and to constrain parameters of the stellar mass function of lens galaxies. Thi…
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…
J17218842: a gravitationally lensed binary quasar with a proximate damped Lyman- absorber
C. Lemon, M. Millon, D. Sluse +5
High-redshift binary quasars provide key insights into mergers and quasar activity, and are useful tools for probing the spatial kinematics and chemistry of galaxies along the line…
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…
HOLISMOKES -- VII. Time-delay measurement of strongly lensed Type Ia supernovae using machine learning
S. Huber, S. H. Suyu, D. Ghoshdastidar +7
The Hubble constant () is one of the fundamental parameters in cosmology, but there is a heated debate around the 4 tension between the local Cepheid distance ladder and…
