Patterns in the CMB: Temperature and Polarization Around Hot Spots (IMAGE)
Caption
4 deg ×4 deg stacks of T, Qr , Ur , E and B on peaks in T for Planck SMICA (row 1), an ACT night-only coadd map (row 2), an ACT+Planck day+night coadd map (row 3), and a beam-less, noise-less simulation (row 4). These stacks are closely related to the CMB autocorrelation function, and give a simple way to illustrate the causal structure of the surface of last scattering. The outermost circle at 1.2 deg represents the autocorrelation of the 0.6 deg sound horizon at the surface of last scattering. The images are normalized to give the outer ring an amplitude of 1 (Ur and B where there is no ring use the same normalization as (Qr and E respectively). Peak detection was done separately for each map, and beam deconvolution was performed. See appendix H for details on the peak detection and stacking procedure.
