*Inverse Compton scattering* is a process where high-energy electrons transfer some of their energy to low-energy photons, resulting in an increase in the photons' energy. This typically occurs in astrophysical environments, such as around pulsars or in the vicinity of black holes, where high-energy electrons are abundant. The process is essential in explaining the presence of high-energy gamma rays observed in various cosmic phenomena and contributes significantly to our understanding of the universe.
