PSZ2 G181.06+48.47 III: weak-lensing analysis and merging scenario reconstruction of a low-mass cluster with exceptionally-distant radio relics
Eunmo Ahn, Hyejeon Cho, M. James Jee +7
The galaxy cluster PSZ2 G181.06+48.47 () is a post-merging system that exhibits symmetric double radio relics separated by ~2.7 Mpc. We present the first weak-lensing anal…
PSZ2 G181.06+48.47 II: radio analysis of a low-mass cluster with exceptionally-distant radio relics
Kamlesh Rajpurohit, Andra Stroe, Ewan O'Sullivan +13
We report upgraded Giant Metrewave Radio Telescope and Karl J. Jansky Very Large Array radio observations of a low-mass merging galaxy cluster PSZ2 G181.06+48.47. This exceptional…
SZ-X-ray Surface Brightness Fluctuations in the SPT-XMM clusters
Charles Romero, Massimo Gaspari, Gerrit Schellenberger +10
The hot plasma in galaxy clusters, the intracluster medium (ICM), is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanis…
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…
Cosmological Constraints from Galaxy Clusters in the 2500 square-degree SPT-SZ Survey
T. de Haan, B. A. Benson, L. E. Bleem +74
(abridged) We present cosmological constraints obtained from galaxy clusters identified by their Sunyaev-Zel'dovich effect signature in the 2500 square degree South Pole Telescope…
Frontier Fields Clusters: Chandra and JVLA View of the Pre-Merging Cluster MACS J0416.1-2403
G. Ogrean, R. van Weeren, C. Jones +26
Merging galaxy clusters leave long-lasting signatures on the baryonic and non-baryonic cluster constituents, including shock fronts, cold fronts, X-ray substructure, radio halos, a…
