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…

Discovery of a large-scale bent radio jet in the merging cluster Abell 514

Wonki Lee, John ZuHone, M. James Jee +3

We report a discovery of a large-scale bent radio jet in the merging galaxy cluster Abell 514 (). The radio emission originates from the two radio lobes of the AGN locat…

Weak-lensing mass bias in merging galaxy clusters

Wonki Lee, Sangjun Cha, M. James Jee +6

Although weak lensing (WL) is a powerful method to estimate a galaxy cluster mass without any dynamical assumptions, a model bias can arise when the cluster density profile departs…

Simulating Jellyfish Galaxies: A Case Study for a Gas-Rich Dwarf Galaxy

Jaehyun Lee, Taysun Kimm, Jérémy Blaizot +5

We investigate the formation of jellyfish galaxies using radiation-hydrodynamic simulations of gas-rich dwarf galaxies with a multi-phase interstellar medium (ISM). We find that th…

Multiwavelength Analysis of A1240, the Double Radio Relic Merging Galaxy Cluster Embedded in a ~80 Mpc-long Cosmic Filament

Hyejeon Cho, M. James Jee, Rory Smith +2

We present a multiwavelength study of the double radio relic cluster A1240 at z=0.195. Our Subaru-based weak lensing analysis detects three mass clumps forming a ~4 Mpc filamentary…
