Relics in galaxy clusters at high radio frequencies
Maja Kierdorf, Rainer Beck, Matthias Hoeft +4
We observed three radio relics in galaxy clusters and one radio relic candidate at 4.85 and 8.35 GHz in total emission and linearly polarized emission with the Effelsberg 100-m tel…
Deep Chandra observations of NGC 1404: cluster plasma physics revealed by an infalling early-type galaxy
Yuanyuan Su, Ralph P. Kraft, Elke Roediger +6
The intracluster medium (ICM), as a magnetized and highly ionized fluid, provides an ideal laboratory to study plasma physics under extreme conditions that cannot yet be achieved o…
Capturing the 3D Motion of an Infalling Galaxy via Fluid Dynamics
Yuanyuan Su, Ralph P. Kraft, Paul E. J. Nulsen +6
The Fornax Cluster is the nearest galaxy cluster in the southern sky. NGC 1404 is a bright elliptical galaxy falling through the intracluster medium of the Fornax Cluster. The shar…
A Spectacular Bow Shock in the 11 keV Galaxy Cluster Around 3C 438
Deanna L. Emery, Akos Bogdan, Ralph P. Kraft +4
We present results of deep 153 ks Chandra observations of the hot, 11 keV, galaxy cluster associated with the radio galaxy 3C 438. By mapping the morphology of the hot gas and anal…
SPT-GMOS: A Gemini/GMOS-South Spectroscopic Survey of Galaxy Clusters in the SPT-SZ Survey
M. B. Bayliss, J. Ruel, C. W. Stubbs +75
We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified…
Testing for X-ray-SZ Differences and Redshift Evolution in the X-ray Morphology of Galaxy Clusters
D. Nurgaliev, M. McDonald, B. A. Benson +12
We present a quantitative study of the X-ray morphology of galaxy clusters, as a function of their detection method and redshift. We analyze two separate samples of galaxy clusters…
