Radio relics in massive galaxy cluster mergers in the TNG-Cluster simulation
W. Lee, A. Pillepich, J. ZuHone +4
Radio relics are diffuse synchrotron sources in the outskirts of merging galaxy clusters energized by the merger shocks. In this paper, we present an overview of the radio relics i…
Weak-Lensing Analysis of the Complex Cluster Merger Abell 746 with Subaru/Hyper Suprime-Cam
Kim HyeongHan, Hyejeon Cho, M. James Jee +15
The galaxy cluster Abell 746 (A746; =0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intr…
Abell 746: A highly disturbed cluster undergoing multiple mergers
K. Rajpurohit, L. Lovisari, A. Botteon +21
We present deep XMM-Newton, Karl Jansky Very Large Array, and upgraded Giant Metrewave Radio Telescope observations of Abell 746, a cluster that hosts a plethora of diffuse emissio…
A New Galaxy Cluster Merger Capable of Probing Dark Matter: Abell 56
David Wittman, Rodrigo Stancioli, Kyle Finner +3
We report the discovery of a binary galaxy cluster merger via a search of the redMaPPer optical cluster catalog, with a projected separation of 535 kpc between the BCGs. Archival X…
A New Dissociative Galaxy Cluster Merger: RM J150822.0+575515.2
Rodrigo Stancioli, David Wittman, Kyle Finner +1
Galaxy cluster mergers that exhibit clear dissociation between their dark matter, intracluster gas, and stellar components are great laboratories for probing dark matter properties…
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…
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…
