Where Cluster Galaxies Reside and How Strongly They Lens
Isaque Dutra, Priyamvada Natarajan, Cian Roche
The efficiency of galaxy-galaxy strong lensing (GGSL) in clusters depends jointly on the inner mass distributions of member galaxies and their locations within the cluster potentia…
SLICE: Unveiling the Multi-Component Merging Core of SPT-CLJ1150-2805 Through Strong-Lensing Mass Modelling
James R. Betts, Benjamin Beauchesne, Mathilde Jauzac +16
We present a new strong-lensing and X-ray mass model of the merging galaxy cluster SPT-CLJ1150-2805 (), combining JWST NIRCam, HST, Chandra, and VLT/MUSE data to robustly…
Host Dependence and Line-of-Sight Effects on Galaxy-Galaxy Strong Lensing in Clusters
Cian Roche, Michael McDonald, Priyamvada Natarajan +4
The cross section for galaxy-galaxy strong lensing (GGSL) events in galaxy clusters has repeatedly been found to be higher in observations than in cosmological simulations. We revi…
A Consistent Implementation of Cluster Strong Lensing in Cosmological Simulation Light Cones
Cian Roche, Mark Vogelsberger, Michael McDonald +9
Galaxy cluster strong gravitational lensing plays a central role in precision cosmology, yet robust theoretical predictions have lagged behind an abundance of high-quality strong l…
New Cold Dark Matter Crisis Revealed by Multiscale Cluster Lensing
Priyamvada Natarajan, Barry T. Chiang, Isaque Dutra
The properties of substructure in galaxy clusters, exquisitely probed by gravitational lensing, offer a stringent test of dark matter (DM) models. Combining strong- and weak-lensin…
