Chandra observations of the galaxy cluster A478: the interaction of hot gas and radio plasma in the core, and an improved determination of the Compton y-parameter
M. Sun, C. Jones, S. S. Murray +3
We present the results from a 42 ks \chandra ACIS observation of the galaxy cluster A478. This cluster is generally considered to be highly relaxed. The \chandra image reveals, for…
Exciting molecular hydrogen in the central galaxies of cooling flows
R. J. Wilman, A. C. Edge, R. M. Johnstone +3
The origin of rovibrational H_2 emission in the central galaxies of cooling flow clusters is poorly understood. Here we address this issue using data from our near-infrared spectro…
A survey of molecular hydrogen in the central galaxies of cooling flows
A. C. Edge, R. J. Wilman, R. M. Johnstone +3
We present a large sample of H- and K-band spectra of 32 optically line luminous central cluster galaxies. We find significant rovibrational H_2 emission in 23 of these galaxies as…
