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…

Nine lensed quasars and quasar pairs discovered through spatially-extended variability in Pan-STARRS

Frédéric Dux, Cameron Lemon, Frédéric Courbin +7

We present the proof-of-concept of a method to find strongly lensed quasars using their spatially-extended photometric variability through difference imaging in cadenced imaging su…

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…

Evidence for a milliparsec-separation Supermassive Binary Black Hole with quasar microlensing

M. Millon, C. Dalang, C. Lemon +4

We report periodic oscillations in the 15-year long optical light curve of the gravitationally lensed quasar QJ0158-4325. The signal is enhanced during a high magnification microle…
