Compton–Getting effect

The Compton-Getting effect is a phenomenon in astrophysics and cosmic ray physics related to the movement of cosmic rays and their interaction with the Earth's atmosphere or a moving observer. Named after the physicist Arthur Holly Compton, this effect describes how the observed intensity and energy distribution of cosmic rays change due to the motion of the observer relative to the incoming cosmic rays. When an observer (such as Earth) moves through space, it can encounter cosmic rays that have a specific energy spectrum.
