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…
Merger Hydrodynamics of the Luminous Cluster RXJ1347.5-1145
C. D. Kreisch, M. E. Machacek, C. Jones +1
We present an analysis of the complex gas hydrodynamics in the X-ray luminous galaxy cluster RXJ1347.5-1145 caught in the act of merging with a subcluster to its southeast using a…
Searching for the 3.5 keV Line in the Stacked Suzaku Observations of Galaxy Clusters
Esra Bulbul, Maxim Markevitch, Adam Foster +5
We perform a detailed study of the stacked Suzaku observations of 47 galaxy clusters, spanning a redshift range of 0.01-0.45, to search for the unidentified 3.5 keV line. This samp…
Multi-wavelength Observations of the Dissociative Merger in the Galaxy Cluster CIZA J0107.7+5408
S. W. Randall, T. E. Clarke, R. J. van Weeren +6
We present results based on X-ray, optical, and radio observations of the massive galaxy cluster CIZA J0107.7+5408. We find that this system is a post core passage, dissociative, b…
Radial Profile of the 3.55 keV line out to in the Perseus Cluster
Jeroen Franse, Esra Bulbul, Adam Foster +10
The recent discovery of the unidentified emission line at 3.55 keV in galaxies and clusters has attracted great interest from the community. As the origin of the line remains uncer…
Frontier Fields Clusters: Deep Chandra Observations of the Complex Merger MACS J1149.6+2223
G. A. Ogrean, R. J. van Weeren, C. Jones +24
The HST Frontier Fields cluster MACS J1149.6+2223 is one of the most complex merging clusters, believed to consist of four dark matter halos. We present results from deep (365 ks)…
