A halo model approach for mock catalogs of time-variable strong gravitational lenses
Katsuya T. Abe, Masamune Oguri, Simon Birrer +5
Time delays in both galaxy- and cluster-scale strong gravitational lenses have recently attracted a lot of attention in the context of the Hubble tension. Future wide-field cadence…
Microlensing of lensed supernovae Zwicky & iPTF16geu: constraints on the lens galaxy mass slope and dark compact object fraction
Nikki Arendse, Edvard Mörtsell, Luke Weisenbach +9
To date, only two strongly lensed type Ia supernovae (SNIa) have been discovered with an isolated galaxy acting as the lens: iPTF16geu and SN Zwicky. The observed image fluxes for…
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…
A Natural Telescope: Discovery of the Strongly Lensed Type II SN 2025mkn at
Cameron Lemon, Ariel Goobar, Joel Johansson +90
We present the discovery of SN 2025mkn, a gravitationally lensed Type II supernova. First detected as a blue transient in ZTF, 0.83 from a elliptical gala…
Strong Lensing Science Collaboration input to the on-sky commissioning of the Vera Rubin Observatory
Graham P. Smith, Timo Anguita, Simon Birrer +10
We present the Strong Lensing Science Collaboration's (SLSC) recommended observing targets for the science verification and science validation phases of commissioning. Our recommen…
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…
