The namesake suppression of this effect is designed to counteract the names
The namesake suppression of this effect is designed to counteract the namesake edge, which is the highest energy at which false spectra are obtained due to incomplete detection.  A related effect can be broken down to include the Ostriker-Vishniac effect and has been used to observe dense galaxy clusters through perturbations of the CMB. That effect, the Sunyaev-Zel'dovich, is the inverse of this process, which has its differential cross section described by the Klein-Nishina formula and includes a constant known as its wavelength. For 10 points, name this effect in which the namesake shift describes the change in wavelength of a photon colliding with an electron.

Compton effect or scattering or shift, etc.
