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…
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…
STARRED: a two-channel deconvolution method with Starlet regularization
Kevin Michalewicz, Martin Millon, Frédéric Dux +1
The spatial resolution of astronomical images is limited by atmospheric turbulence and diffraction in the telescope optics, resulting in blurred images. This makes it difficult to…
