Joint JWST-DECam Lensing Reveals That the Bullet Cluster Is a Minor Merger

Boseong Young Cho, M. James Jee, Hyungjin Joo +2

We present the first robust virial masses of the Bullet Cluster's three individual components from a joint weak+strong lensing analysis combining JWST/NIRCam and DECam observations…

Exploring the statistical properties of double radio relics in the TNG-Cluster and TNG300 simulations

Wonki Lee, Annalisa Pillepich, Dylan Nelson +4

Double radio relics, pairs of diffuse radio features located on opposite sides of merging galaxy clusters, are a rare subclass of radio relics that are believed to trace merger sho…

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…
