Compton–Getting effect (original) (raw)

The Compton–Getting effect is an apparent anisotropy in the intensity of radiation or particles due to the relative motion between the observer and the source. This effect was first identified in the intensity of cosmic rays by Arthur Compton and Ivan A. Getting in 1935. Gleeson and Axford provide a full derivation of the equations relevant to this effect. This Compton–Getting effect is apparent in plasma data in Earth's magnetotail. The Compton–Getting effect has also been utilized for analyzing energetic neutral atom (ENA) data returned by the Cassini-Huygens spacecraft at Saturn.
