NED Abstract

Copyright by Royal Astronomical Society. 1997MNRAS.290..577R The extended radio emission in the luminous X-ray cluster A3667 H. J. A. Rottgering, M. H. Wieringa, R. W. Hunstead and R. D. Ekers Accepted 1997 March 10. Received 1997 February 18 ABSTRACT The radio sources in the galaxy cluster A3667 have been imaged using the Australia Telescope Compact Array at both 13 and 20 cm. The most striking source is a large region (at least 2.6 Mpc in extent) of mostly diffuse emission that is located to the north-west, well outside the central core of the cluster. Taking into account the X-ray and optical data, we suggest that turbulence in the outer region of the cluster, associated with a cluster merger, reaccelerates remnant relativistic particles, leading to the observed large region of radio emission. New MOST data which indicate similar diffuse emission to the south-east support this conclusion. Key words: galaxies: clusters: individual: A3667 - radio continuum: galaxies.
