A Merger Shock in Abell 2034
Matt S. Owers, Paul E. J. Nulsen, Warrick J. Couch +6
We present a ks Chandra observation of the cluster merger A2034 with the aim of understanding the nature of a sharp edge previously characterized as a cold front. The new da…
The origin of cold gas in giant elliptical galaxies and its role in fueling radio-mode AGN feedback
N. Werner, J. B. R. Oonk, M. Sun +12
We present a multi-wavelength study of the interstellar medium in eight nearby, X-ray and optically bright, giant elliptical galaxies. Using Herschel PACS, we map the cold gas in t…
The narrow X-ray tail and double H-alpha tails of ESO 137-002 in Abell 3627
B. Zhang, M. Sun, L. Ji +9
We present the analysis of a deep Chandra observation of a ~2L_* late-type galaxy, ESO 137-002, in the closest rich cluster A3627. The Chandra data reveal a long (>40 kpc) and narr…
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…
Massive molecular gas flows in the Abell 1664 brightest cluster galaxy
H. R. Russell, B. R. McNamara, A. C. Edge +14
We report ALMA Early Science CO(1-0) and CO(3-2) observations of the brightest cluster galaxy (BCG) in Abell 1664. The BCG contains 1.1x10^{10} solar masses of molecular gas divide…
A Ten Billion Solar Mass Outflow of Molecular Gas Launched by Radio Bubbles in the Abell 1835 Brightest Cluster Galaxy
B. R. McNamara, H. R. Russell, P. E. J. Nulsen +17
We report ALMA Early Science observations of the Abell 1835 brightest cluster galaxy (BCG) in the CO (3-2) and CO (1-0) emission lines. We detect 5E10 solar masses of molecular gas…
