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…
The High-Redshift Clusters Occupied by Bent Radio AGN (COBRA) Survey: Investigating the Role of Environment on Bent Radio AGNs using LOFAR
Emmet Golden-Marx, Emily Moravec, Lu Shen +10
Bent radio AGN morphology depends on the density of the surrounding gas. However, bent sources are found inside and outside clusters, raising the question of how environment impact…
Chandra X-Ray Observations of Abell 119: Cold Fronts And A Shock In An Evolved Off-Axis Merger
Courtney B. Watson, Elizabeth L. Blanton, Scott W. Randall +4
We present Chandra X-ray observations of the dynamically complex galaxy cluster Abell 119 (). A119 is host to two NAT radio sources (0053-015 & 0053-016) whose tails are…
Multiple shock fronts in RBS 797: the Chandra window on shock heating in galaxy clusters
F. Ubertosi, M. Gitti, F. Brighenti +11
Using 427 ks of Chandra observations, we present a study of shock heating and ICM cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roug…
HST and HSC Weak-lensing Study of the Equal-mass Dissociative Merger CIZA J0107.7+5408
Kyle Finner, Scott W. Randall, M. James Jee +6
A dissociative merger is formed by the interplay of ram pressure and gravitational forces, which can lead to a spatial displacement of the dark matter and baryonic components of th…
Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
