Top panel: the comparative radio structure of ID 11 detected via the ATLAS data and the NVSS data. The radio contours based on the ATLAS, convolved ATLAS, and VLA data are shown with the green solid, red dashed, and blue dotted contours, respectively. The black circles represent the galaxy members of the A3141 cluster. Bottom left panel: the spatial distribution of galaxies in the galaxy cluster A3141. The approximate extent of A3141 is shown by a circle with the Abell radius (~1.87 Mpc). The location of ID 11 is shown by a blue cross. Bottom right panel: the redshift distribution of galaxies within ~15′ of ID 11. The blue dashed line represents the redshift location of the BT in the A3141 cluster. The data were extracted from the 2dFGRS (Colless et al. 2003) and the Southern Abell Redshift Survey (SARS; Way et al. 2005).
