The Dissection of Abell 2744: A Rich Cluster Growing Through Major and Minor Mergers
Matt S. Owers, Scott W. Randall, Paul E. J. Nulsen +3
New Chandra X-ray data and extensive optical spectroscopy, obtained with AAOmega on the 3.9 m Anglo-Australian Telescope, are used to study the complex merger taking place in the g…
The architecture of Abell 1386 and its relationship to the Sloan Great Wall
Kevin A. Pimbblet, Heinz Andernach, Cherie K. Fishlock +2
We present new radial velocities from AAOmega on the Anglo-Australian Telescope for 307 galaxies (b_J < 19.5) in the region of the rich cluster Abell 1386. Consistent with other st…
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…
Synchronized formation of starburst and poststarburst galaxies in merging clusters of galaxies
Kenji Bekki, Matt S. Owers, Warrick J. Couch
We propose that synchronized triggering of star formation in gas-rich galaxies is possible during major mergers of cluster of galaxies, based on new numerical simulations of the ti…
