Galaxy groups and analysed galaxies in the Cold Spot area. In the upper plots, grey circles show the galaxy groups from Fig. 5 of Brough et al. (2006). In the lower plots, grey circles show the subspots as defined in Cruz et al. (2005). In the upper left plot these subspots are shown as red circles. Upper-left panel: CMB Cold Spot. Right panels: galaxies from 6dF (upper) and HIPASS (lower) catalogues, colour-coded with redshift. Lower-left panel: 2MRS spirals colour coded with galaxy size.
