Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy

Gregor Rihtaršič, Maruša Bradač, Guillaume Desprez +23

We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…

A Deep Chandra View of Abell 2597: Bubbles, Shocks, Cold Fueling, and a Plasma Depletion Layer

Osase Omoruyi, Grant Tremblay, Stefi A. Baum +14

To examine how AGN feedback shapes the intracluster medium (ICM) and fuels black hole accretion in the cool-core galaxy cluster Abell 2597, we present deep (600 ks) Chandra X…

Understanding the Nature of the Ultra-Steep Spectrum Diffuse Radio Source in the Galaxy Cluster Abell 272

Arthur Whyley, Scott W. Randall, Tracy E. Clarke +7

Ultra-steep spectrum (USS) radio sources with complex filamentary morphologies are a poorly understood subclass of diffuse radio source found in galaxy clusters. They are character…

On the Particle Acceleration Mechanisms in a Double Radio Relic Galaxy Cluster, Abell 1240

Arnab Sarkar, Felipe Andrade-Santos, Reinout J. van Weeren +12

We present a 368 ks deep Chandra observation of Abell~1240, a binary merging galaxy cluster at a redshift of 0.195 with two Brightest Cluster Galaxies (BCGs) may have passed each o…

AMUSE-antlia I: Nuclear X-ray properties of early-type galaxies in a dynamically young galaxy cluster

Zhensong Hu, Yuanyuan Su, Zhiyuan Li +14

To understand the formation and growth of supermassive black holes (SMBHs) and their co-evolution with host galaxies, it is essential to know the impact of environment on the activ…
