Pulsar wind nebulae research focuses on the relativistic outflows of electron–positron pairs and magnetic fields driven by rapidly rotating, highly magnetized neutron stars, and on the resulting non-thermal nebulae produced as these winds interact with their surroundings. This area integrates high-energy astrophysics, plasma physics, and magnetohydrodynamics to study particle acceleration, shock formation, magnetic field amplification, and radiation processes (synchrotron and inverse Compton) spanning radio to TeV gamma rays. It also investigates PWN evolution within supernova remnants and the interstellar medium, their morphology, and their role as laboratories for cosmic-ray production and magnetized relativistic plasmas.
Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 light-years ...
