"Unraveling Cosmic Mysteries: Black Hole Jets and Relativistic Particles"
Observations from the High Energy Stereoscopic System (HESS) in Namibia have identified the origin of high-energy cosmic rays to a region near a black hole in the Manatee Nebula. These findings shed light on the century-old mystery of cosmic ray origins and suggest that smaller black holes, known as microquasars, could contribute to the cosmic-ray population. The study's precise gamma-ray observations indicate that the cosmic rays are produced by mechanisms internal to the jets, rather than by collisions with other matter, strengthening the case for X-ray binaries as smaller analogues to supermassive black holes capable of accelerating cosmic rays.
