Precision Measurement of Large Shear Signals
Jiarui Sun, Jun Zhang, Li Cui +2
So far, estimators of galaxy shape distortions are only carefully studied perturbatively in the case of small shear signals, mainly for weak lensing science. However, in the neighb…
TDCOSMO 2025: Cosmological constraints from strong lensing time delays
TDCOSMO Collaboration, Simon Birrer, Elizabeth J. Buckley-Geer +30
We present cosmological constraints from 8 strongly lensed quasars (hereafter, the TDCOSMO-2025 sample). Building on previous work, our analysis incorporated new deflector stellar…
Caustic area biases and how to deal with them
Alessandro Sonnenfeld
Quadruply-imaged strongly lensed quasars (quads) are routinely used for measurements of the expansion rate of the Universe with time delays. It has recently been suggested that any…
Constraining galaxy properties with complete samples of lenses
Qing Zhou, Alessandro Sonnenfeld, Henk Hoekstra
The statistics of Einstein radii for a sample of strong lenses can provide valuable constraints on the underlying mass distribution. The correct interpretation, however, relies cri…
Neural network prediction of model parameters for strong lensing samples from Hyper Suprime-Cam Survey
Priyanka Gawade, Anupreeta More, Surhud More +4
Strong lensing of background galaxies provides important information about the matter distribution around lens galaxies. Traditional modelling of such strong lenses is both time an…
Photometric redshift estimation of strongly lensed galaxies
Danial Langeroodi, Alessandro Sonnenfeld, Henk Hoekstra +1
Around strongly lensed galaxies are expected to be discovered with Euclid and the LSST. Utilising these large samples to study the inner structure of lens galaxies requires…
