radio lobes

Radio lobes are large regions of energetic particles and magnetic fields located at the ends of certain galaxies with active nuclei. They are formed by streams of charged particles propelled at near-light speeds from the galaxy's core, where supermassive black holes reside. As these particles travel outward, they interact with magnetic fields, producing powerful radio wave emissions that we detect as lobes. These structures can extend hundreds of thousands of light-years, providing insight into the galaxy's black hole activity and the influence of powerful jets on the surrounding environment.
