Observations of high energy phenomena in astrophysics have advanced remarkably in the past decade. With gamma-ray telescopes and high resolution x-ray telescopes we can now observe particle acceleration to TeV energies as and where it occurs, and cosmic ray detectors give a much improved picture of the spectrum and composition of accelerated particles. New observations have led to new theories based on physics related to that of magnetic field generation and energetic electron transport in laser-produced plasmas.
