Neutrino self-interactions in the CMB temperature spectrum
How varying the effective neutrino coupling changes the CMB temperature spectrum and its difference from the standard-neutrino reference.
Two panels compare the CMB temperature spectrum for standard and self-interacting neutrinos, and show the percentage difference in TT angular power as a function of multipole.

About this visualization
The upper panel compares the CMB temperature spectrum for standard neutrinos (dashed gray) and self-interacting neutrinos (blue). As the effective coupling G_eff changes, the lower panel shows the percentage difference in the TT angular power spectrum relative to the standard-neutrino case.
The graphic identifies the calculation as Modified CLASS — NSI_cato. Its changing coupling label and the shared multipole axis make the scale dependence of the spectral changes visible.
