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…
Chandra and JVLA observations of HST Frontier Fields cluster MACS J0717.5+3745
R. J. van Weeren, G. A. Ogrean, C. Jones +24
To investigate the relationship between thermal and non-thermal components in merger galaxy clusters, we present deep JVLA and Chandra observations of the HST Frontier Fields clust…
Resolving the Merging Planck Cluster PLCK G147.3-16.6 with GISMO
T. Mroczkowski, A. Kovács, E. Bulbul +6
The satellite has recently completed an all-sky galaxy cluster survey exploiting the thermal Sunyaev-Zel'dovich (SZ) effect to locate some of the most massive systems obse…
Chandra View of the Ultra-Steep Spectrum Radio Source in Abell 2443: Merger Shock-Induced Compression of Fossil Radio Plasma?
T. E. Clarke, S. W. Randall, C. L. Sarazin +2
We present a new Chandra X-ray observation of the intracluster medium in the galaxy cluster Abell 2443, hosting an ultra-steep spectrum radio source. The data reveal that the intra…
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…
A multi-wavelength view of cooling vs. AGN heating in the X-ray luminous cool-core of Abell 3581
R. E. A. Canning, M. Sun, J. S. Sanders +12
We report the results of a multi-wavelength study of the nearby galaxy group, Abell 3581 (z=0.0218). This system hosts the most luminous cool core of any nearby group and exhibits…
Multiphase Signatures of AGN Feedback in Abell 2597
G. R. Tremblay, C. P. O'Dea, S. A. Baum +18
We present new Chandra X-ray observations of the brightest cluster galaxy (BCG) in the cool core cluster Abell 2597. The data reveal an extensive kpc-scale X-ray cavity network as…
A Very Deep Chandra Observation of Abell 2052: Bubbles, Shocks, and Sloshing
E. L. Blanton, S. W. Randall, T. E. Clarke +4
We present first results from a very deep (~650 ksec) Chandra X-ray observation of Abell 2052, as well as archival VLA radio observations. The data reveal detailed structure in the…
The Merger Environment of the WAT Hosting Cluster Abell 562
E. M. Douglass, Elizabeth L. Blanton, T. E. Clarke +2
We present a Chandra X-ray observation and VLA radio observations of the nearby (z=0.11) galaxy cluster Abell 562 and the wide angle tail (WAT) radio source 0647+693. The cluster d…
Radio and Deep Chandra Observations of the Disturbed Cool Core Cluster Abell 133
S. W. Randall, T. E. Clarke, P. E. J. Nulsen +4
We present results based on new Chandra and multi-frequency radio observations of the disturbed cool core cluster Abell 133. The diffuse gas has a complex bird-like morphology, wit…
Active galactic nucleus feedback in clusters of galaxies
Elizabeth L. Blanton, T. E. Clarke, Craig L. Sarazin +2
Observations made during the last ten years with the Chandra X-ray Observatory have shed much light on the cooling gas in the centers of clusters of galaxies and the role of active…
