TNGC-SIDM I: Evolution of massive cluster mergers under the self-interacting dark matter paradigm
Wonki Lee, Dylan Nelson, Myungkook J. Jee +8
Merging galaxy clusters provide an ideal laboratory for testing the self-interacting nature of dark matter. In this paper, we present a pilot study of magnetohydrodynamical cosmolo…
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 New Robust Constraint on the Self-interaction Cross-section of Dark Matter with Double Radio Relic Clusters
M. James Jee, Dongak Park, Wonki Lee
Merging galaxy clusters are a promising laboratory for measuring the self-interaction cross-section (SICS) of dark matter. However, previous studies have focused on galaxy-mass off…
Weak-Lensing Analysis of the Galaxy Cluster Abell 85: Constraints on the Merger Scenarios of Its Southern Subcluster
Soojin Kim, Kim HyeongHan, Wonki Lee +3
Abell 85 is a nearby (z=0.055) galaxy cluster that hosts a sloshing cool core, a feature commonly reported in relaxed clusters. However, the presence of multiple past and ongoing m…
PSZ2 G181.06+48.47 III: weak-lensing analysis and merging scenario reconstruction of a low-mass cluster with exceptionally-distant radio relics
Eunmo Ahn, Hyejeon Cho, M. James Jee +7
The galaxy cluster PSZ2 G181.06+48.47 () is a post-merging system that exhibits symmetric double radio relics separated by ~2.7 Mpc. We present the first weak-lensing anal…
PSZ2 G181.06+48.47 II: radio analysis of a low-mass cluster with exceptionally-distant radio relics
Kamlesh Rajpurohit, Andra Stroe, Ewan O'Sullivan +13
We report upgraded Giant Metrewave Radio Telescope and Karl J. Jansky Very Large Array radio observations of a low-mass merging galaxy cluster PSZ2 G181.06+48.47. This exceptional…
Weak-Lensing Characterization of the Dark Matter in 29 Merging Clusters that Exhibit Radio Relics
Kyle Finner, M. James Jee, Hyejeon Cho +5
We present a multiwavelength analysis of 29 merging galaxy clusters that exhibit radio relics. For each merging system, we perform a weak-lensing analysis on Subaru optical imaging…
Substructures within Substructures in the Complex Post-Merging System A514 Unveiled by High-Resolution Magellan/Megacam Weak Lensing
Eunmo Ahn, M. James Jee, Wonki Lee +2
Abell 514 (A514) at is an intriguing merging system exhibiting highly elongated (~1 Mpc) X-ray features and three large-scale (300~500 kpc) bent radio jets. To dissect th…
