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…
Surface Brightness Fluctuations in Two SPT clusters: a Pilot Study
Charles E. Romero, Massimo Gaspari, Gerrit Schellenberger +10
Studies of surface brightness fluctuations in the intracluster medium (ICM) present an indirect probe of turbulent properties such as the turbulent velocities, injection scales, an…
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…
Viscous Kelvin-Helmholtz instabilities in highly ionised plasmas
E. Roediger, R. P. Kraft, P. Nulsen +4
Transport coefficients in highly ionised plasmas like the intra-cluster medium (ICM) are still ill-constrained. They influence various processes, among them the mixing at shear flo…
Complex diffuse radio emission in the merging PLANCK ESZ cluster Abell 3411
R. J. van Weeren, K. Fogarty, C. Jones +7
We present VLA radio and Chandra X-ray observations of the merging galaxy cluster Abell 3411. For the cluster, we find an overall temperature of 6.4 keV and an X-ray luminosity of…
Radio-loud AGN: is there a link between luminosity and cluster environment?
J. Ineson, J. H. Croston, M. J. Hardcastle +3
We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project, characterizing the cluster environments of a sample of 26 radio-loud AGN at z…
Kelvin-Helmholtz instabilities at the sloshing cold fronts in the Virgo cluster as a measure for the effective ICM viscosity
E. Roediger, R. P. Kraft, W. R. Forman +2
Sloshing cold fronts (CFs) arise from minor merger triggered gas sloshing. Their detailed structure depends on the properties of the intra-cluster medium (ICM): hydrodynamical simu…
Chandra Observation of 3C288 - Reheating the Cool Core of a 3 keV Cluster from a Nuclear Outburst at z = 0.246
D. V. Lal, R. P. Kraft, W. R. Forman +6
We present results from a 42 ks Chandra/ACIS-S observation of the transitional FRI/FRII radio galaxy 3C288 at z = 0.246. We detect 3 keV gas extending to a radius of 0.…
Parsec-scale Imaging of the Radio-bubble Seyfert galaxy NGC 6764
P. Kharb, Ananda Hota, J. H. Croston +5
We have observed the composite active galactic nucleus (AGN)-starburst galaxy NGC 6764 with the Very Long Baseline Array at 1.6 and 4.9 GHz. These observations have detected a "cor…
