Scientists from the RIKEN Cluster for Pioneering Research and collaborators have used simulations to show that the photons emitted by long gamma-ray bursts—one of the most energetic events to take place in the universe—originate in the photosphere—the visible portion of the “relativistic jet” that is emitted by exploding stars.
