"Unraveling the Mysteries of Astrophysical Jet Acceleration and Cosmic Rays"
The SS 433 binary star system, known for its collimated jets of charged particles, has been observed to abruptly reappear as bright X-ray sources around 75 light years from their launch site, with gamma-ray emission detected for the first time by the H.E.S.S. Observatory. The gamma-ray emission shows an energy-dependent morphology, with the highest energy photons detected at the point where the jets reappear, while lower energy photons appear further along each jet, providing new insights into the acceleration and transport of relativistic electrons in astrophysical jets.
