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…
Suzaku Observations of the Cluster Outskirts and Intercluster Filament in the Triple Merger Cluster Abell 98
Gabriella E. Alvarez, Scott W. Randall, Yuanyuan Su +5
We present Suzaku observations of the Abell 98 (A98) triple galaxy cluster system and the purported intercluster filament. The three subclusters are expected to lie along a large s…
Probing the Outskirts of the Early Stage Galaxy Cluster Merger A1750
Esra Bulbul, Scott W. Randall, Matthew Bayliss +12
We present results from recent Suzaku and Chandra X-ray, and MMT optical observations of the strongly merging "double cluster" A1750 out to its virial radius, both along and perpen…
Merger Signatures in the Galaxy Cluster Abell 98
Rachel Paterno-Mahler, Scott W. Randall, Esra Bulbul +5
We present results from Chandra and XMM-Newton observations of Abell 98 (A98), a galaxy cluster with three major components: a relatively bright subcluster to the north (A98N), a d…
Deep Chandra Observations of the Extended Gas Sloshing Spiral in A2029
Rachel Paterno-Mahler, Elizabeth L. Blanton, Scott W. Randall +1
Recent X-ray observations of galaxy clusters have shown that there is substructure present in the intracluster medium (ICM), even in clusters that are seemingly relaxed. This subst…
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…
