PSJ2107-1611: a new wide-separation, quadruply imaged lensed quasar with flux ratio anomalies
Frédéric Dux, Cameron Lemon, Frédéric Courbin +4
We report the discovery of PSJ2107-1611, a fold-configuration 4.3"-separation quadruply lensed quasar with a bright lensed arc. It was discovered using a convolutional neural netwo…
JWST lensed quasar dark matter survey I: Description and First Results
A. M. Nierenberg, R. E. Keeley, D. Sluse +18
The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespect…
Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky
Ariel Goobar, Joel Johansson, Steve Schulze +35
Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a s…
STRIDES: Automated uniform models for 30 quadruply imaged quasars
T. Schmidt, T. Treu, S. Birrer +68
Gravitational time delays provide a powerful one step measurement of , independent of all other probes. One key ingredient in time delay cosmography are high accuracy lens mod…
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…
Finding quadruply imaged quasars with machine learning. I. Methods
A. Akhazhanov, A. More, A. Amini +68
Strongly lensed quadruply imaged quasars (quads) are extraordinary objects. They are very rare in the sky -- only a few tens are known to date -- and yet they provide unique inform…
