Columbia Scientists Reveal Magnetic Secrets Behind Ultra-Energetic Cosmic Rays

Ultra-high energy cosmic rays are energized by magnetic turbulence, not shock acceleration, according to new research. Tangled magnetic fields in extreme astrophysical environments propel particles to incredible energies, advancing our understanding of these cosmic phenomena. Ultra-high-energy cosmic rays, originating from some of the most extreme astrophysical environments—such as the turbulent regions near black holes and [...]
