Dark and Luminous Matter in the Coma Cluster: Probing Galaxy Cluster Assembly Through Filaments with Weak Lensing and Multiwavelength Observations

K. HyeongHan, K. Finner, M. James Jee +11

The Coma cluster (Abell 1656; ) is a nearby rich galaxy cluster and a key laboratory for studying cluster assembly in the Cosmic Web. We characterize its projected dark ma…

A stellar dynamical mass measurement of an inactive black hole at redshift 2

Andrew B. Newman, Meng Gu, Sirio Belli +34

Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…

Weak-lensing Analysis of Intracluster Filaments in Abell 2744: Matched-filter Scans and Stepwise 2D Tracing

Sangjun Cha, Kyle Finner, M. James Jee +1

We present a weak-lensing (WL) analysis of filamentary structures in the merging galaxy cluster Abell 2744 using wide-field Magellan/MegaCam imaging data. We employ two complementa…

Mature but Still Growing: JWST Detection of the Earliest Intracluster Light at z ~ 2

Hyungjin Joo, M. James Jee, Kyle Finner +6

We present a JWST analysis of intracluster light (ICL) in XLSSC 122 at z = 1.98, currently the most distant known strong lensing galaxy cluster with an evolved member population. U…

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…
