Fermi Links Nearby Pulsar’s Gamma-ray ‘Halo’ to Antimatter Puzzle | NASA

a photon "squiggle" collides with an electron "dot"; there's a flash and the photon (now a higher-energy gamma ray) shoots away
Particles traveling near light speed can interact with starlight and boost it to gamma-ray energies. This animation shows the process, known as inverse Compton scattering. When light ranging from microwave to ultraviolet wavelengths collides with a fast-moving particle, the interaction boosts it to gamma rays, the most energetic form of light.
