Radio jets as a research area focuses on the formation, propagation, and emission properties of collimated, relativistic outflows from active galactic nuclei, X-ray binaries, and other compact objects, observed primarily at radio wavelengths. This field investigates jet launching mechanisms (e.g., magnetohydrodynamic processes near accreting black holes), particle acceleration, synchrotron and inverse-Compton emission, jet–interstellar/intergalactic medium interactions, and the role of jets in feedback on galaxy and cluster evolution. Research combines high-resolution radio interferometry, multiwavelength observations, numerical simulations, and theoretical modeling to constrain jet composition, energetics, magnetic field structure, and kinematics across different cosmic environments.
Astronomers have discovered an extraordinary new giant radio galaxy with plasma jets 32 times the size of our Milky Way.

An international team of astronomers has observed an extremely radio-loud quasar known as J1601+3102. As a result, they found that the quasar hosts a large extended radio jet. The discovery is reported in a research paper ...
Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei of active galaxies distant ...
