Precision MARS Mass Reconstruction of Abell 2744: Synergizing the Largest Strong Lensing and Densest Weak Lensing Datasets from JWST
Sangjun Cha, Kim HyeongHan, Zachary P. Scofield +2
We present a new high-resolution free-form mass model of Abell 2744, combining both weak-lensing (WL) and strong-lensing (SL) datasets from JWST. The SL dataset comprises 286 multi…
The First Weak-lensing Analysis with the James Webb Space Telescope: SMACS J0723.3-7327
Kyle Finner, Andreas Faisst, Ranga-Ram Chary +1
Utilizing the James Webb Space Telescope Early Release NIRCam Observations, we perform a weak-lensing analysis of the massive galaxy cluster SMACS J0723.3-7327 (). We inves…
Model-Independent Mass Reconstruction of the Hubble Frontier Field Clusters with MARS Based on Self-Consistent Strong Lensing Data
Sangjun Cha, M. James Jee
We present new strong-lensing (SL) mass reconstruction of the six Hubble Frontier Fields (HFF) clusters with the MAximum-entropy ReconStruction () algorithm. ${\tt MARS…
Near-IR Weak-Lensing (NIRWL) Measurements in the CANDELS Fields I: Point-Spread Function Modeling and Systematics
Kyle Finner, Bomee Lee, Ranga-Ram Chary +5
We have undertaken a Near-IR Weak Lensing (NIRWL) analysis of the wide-field CANDELS HST/WFC3-IR F160W observations. With the Gaia proper-motion-corrected catalog as an astrometric…
HST and HSC Weak-lensing Study of the Equal-mass Dissociative Merger CIZA J0107.7+5408
Kyle Finner, Scott W. Randall, M. James Jee +6
A dissociative merger is formed by the interplay of ram pressure and gravitational forces, which can lead to a spatial displacement of the dark matter and baryonic components of th…
Exemplary Merging Clusters: Weak-lensing and X-ray Analysis of the Double Radio Relic Merging Galaxy Clusters MACS 1752.0+4440 and ZWCL 1856.8+6616
Kyle Finner, Kim HyeongHan, M. James Jee +8
The investigation of merging galaxy clusters that exhibit radio relics is strengthening our understanding of the formation and evolution of galaxy clusters, the nature of dark matt…
