Cosmic Rays in Clusters of Galaxies (2002)
Biermann, Peter L., Enßlin, Torsten A., Kang, Hyesung, Lee, Hyesook, Ryu, Dongsu
We argue that clusters of galaxies have an intergalactic medium, which is permeated by strong magnetic fields and also has a contribution of pressure from cosmic rays. These two components of total...
3C 129 at 90 centimeters: Evidence for a radio relic? (2002)
Perley, R. A., Harris, D. E., Enßlin, Torsten A., Kassim, N. E., Lane, W. M.
We present a new wide-field map of the radio galaxy 3C 129 and its companion galaxy 3C 129.1 at lambda = 90 cm. We see a distinct steep-spectrum feature near the head of 3C 129, extending in a...
Particle acceleration and diffusion in fossil radio plasma (2002)
We discuss two themes from Chandra cluster observations. First, we describe the interaction of buoyant, radio emitting plasma bubbles with the hot intracluster gas. Second we summarize the Chandra...
