2014 Science Highlights
Deep radio observations of the radio halo
of the bullet cluster 1E 0657-55.8
Shimwell et al. (2014) present deep 1.1-3.1 GHz Australia Telescope Compact Array observations of the radio halo of the bullet cluster, 1E 0657-55.8. In comparison to existing images of this radio halo, the detection in their images is at higher significance. The radio halo is as extended as the X-ray emission in the direction of cluster merger but is significantly less extended than the X-ray emission in the perpendicular direction. These observations support the theory that shocks and turbulence influence the formation and evolution of radio halo synchrotron emission.
