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…
LoVoCCS. III. Third Generation Pipeline & The Hercules Supercluster
Anthony M. Englert, Shenming Fu, Ian Dell'Antonio +29
The Local Volume Complete Cluster Survey (LoVoCCS) is a volume-complete survey of over one-hundred nearby (), X-ray luminous ($L_{500} > 10^{44} \text{ erg s}^{-1}…
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…
A Kiloparsec-Scale Stellar Cavity in the Center of Abell402-BCG May be Caused by Dynamic Interactions with an Ultramassive Black Hole
Michael McDonald, Gourav Khullar, David Lagattuta +18
We present new observations from JWST NIRCam that reveal a striking kpc-wide cavity in the stellar distribution of the central galaxy in the cluster Abell402. Supporting data from…
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…
