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…
On the Origin of Gas-stripping of Galaxies in Group Environments
Jinsu Rhee, Christophe Pichon, Yohan Dubois +12
We investigate how low-mass group environments () influence the gas content of their satellite galaxies with using…
An Active Galaxy Cluster Merger at Cosmic Noon Revealed by JWST Weak Lensing and Multiwavelength Probes
Zachary P. Scofield, Kyle Finner, Hyungjin Joo +8
The galaxy cluster XLSSC~122 is a rare system at , hosting surprisingly evolved member galaxies when the Universe was only one-third of its present age. Leveraging deep J…
Revealing the magnetization of the intracluster medium of Abell 3581 using background Faraday rotation measures from the POSSUM survey
Affan Khadir, Erik Osinga, Wonki Lee +16
The line-of-sight magnetic field of galaxy clusters can be probed using Faraday rotation measure (RM) data. However, our understanding of cluster magnetism is limited due to the sc…
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…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
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…
A High-Caliber View of the Bullet Cluster Through JWST Strong and Weak Lensing Analyses
Sangjun Cha, Boseong Young Cho, Hyungjin Joo +5
The Bullet Cluster (1E 0657-56) is a key astrophysical laboratory for studying dark matter, galaxy cluster mergers, and shock propagation in extreme environments. Using new JWST im…
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…
PSZ2 G181.06+48.47 I: X-ray exploration of a low-mass cluster with exceptionally-distant radio relics
Andra Stroe, Kamlesh Rajpurohit, Zhenlin Zhu +13
Relics are diffuse, highly-polarized radio sources that trace merger-driven shocks at the periphery of merging galaxy clusters. The LOFAR survey recently discovered a rare example…
