Predicted foregrounds temperature model in the Cold Spot area. Left panel: CMB Cold Spot area. Middle panel: temperature model that we obtain using a linear profile around large spiral galaxies in the 2MRS and HIPASS catalogues as well as 6dF galaxies. Right panel: density of large spiral galaxies where all galaxies in the middle panel have been assigned the same profile depth of 1 (except 6dF galaxies which were assigned a profile depth of 0.2). In the three panels, grey areas indicate [ − 20, −30] μK contours to guide the by-eye comparison with the CMB.
