  This is hard to say. One would need to overlay the radio contours on the optical image to see which galaxy the radio belongs to.

  I would do this but I seem to be having the same issues with my browser as mentioned here: http://radiotalk.galaxyzoo.org/#/boards/BRG0000005/discussions/DRG00006o4?page=1&comment_id=53a1e69f037b30649200049d

  There is more information available here on these "contour explosions".

  It's the big red one in the center, SDSS J105155.38+471937.5, with a spectroscopic redshift of 0.473 (so it's likely the BCG):

  

  Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST contours derived from FITS files produced using SkyView with Python code described in this RGZ Talk thread. Image center per the ARG image (left; J2000).
