What powers the most powerful explosions in the Universe?

A new analysis of archival data of gamma-ray bursts (GRB), the most energetic objects in the Universe, has revealed that the process producing this emission might indeed be electrons that are cooled from near-relativistic speeds in a magnetic field. This so-called synchrotron radiation was dismissed in earlier, more indirect analyses. Scientists at the Max Planck … Read more What powers the most powerful explosions in the Universe?
