Bottom Line • Therefore, the chemical potential is generated by the photon density perturbation squared. • At what scale? The diffusion damping occurs at the mean free path of photons. In terms of the wavenumber, it is given by: It’s a very small scale! (compared to the large-scale structure, k~1 Mpc –1 ) ; 58
μ-distortion modified by the squeezed limit • The existence of long-wavelength ζ changes the smallscale power of δγ. • A positive long-wavelength ζ -> more power on small scales. • More power on small scales -> more μ-distortion. • μ-distortion becomes anisotropic on the sky!
