Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
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 Abell 2199: the Interplay between Merger-Induced Gas Motions and Nuclear Outbursts in a Cool Core Cluster
Paul E. J. Nulsen, Zhiyuan Li, William R. Forman +9
We present new Chandra observations of Abell 2199 that show evidence of gas sloshing due to a minor merger, as well as impacts of the radio source, 3C 338, hosted by the central ga…
Sloshing Gas in the Core of the Most Luminous Galaxy Cluster RXJ1347.5-1145
Ryan E. Johnson, John A. ZuHone, Christine Jones +2
We present new constraints on the merger history of the most X-ray luminous cluster of galaxies, RXJ1347.5-1145, based its unique multiwavelength morphology. Our X-ray analysis con…
Core Gas Sloshing in Abell 1644
Ryan E. Johnson, Maxim Markevitch, Gary A. Wegner +2
We present an analysis of a 72 ks Chandra observation of the double cluster Abell 1644 (z=0.047). The X-ray temperatures indicate the masses are M500=2.6+/-0.4 x10^{14} h^{-1} M_su…
