SZ effect: the standard lore thermal NR e - I 0 (x) I(x)

The origin of the SZ effect 1957 A.S. Kompaneets publishes his Compton scattering Fokker-Planck equation 1969 Ya. B. Zel’dovich & R. Sunyaev derive the SZ effect (i.e., applied the Kompaneets eq.) for a thermal intracluster plasma Non-coherent Compton Scattering Fall-out effect of the Cold War (derived by A.S. Kompaneets in Soviet Union  1950 but was classified due to bomb research until 1956)
