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.
Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding ...

Astronomers have reported the discovery of an unusual X-ray transient detected by the Einstein Probe that does not fit any known class of cosmic explosions. The paper presenting its multiwavelength analysis was published ...
Astronomers have discovered a "remarkable" bow-and-arrow-shaped radio galaxy with an enormous arc-like structure extending nearly 1.8 million light-years across. The newly identified system, detailed in a new paper published ...

Astronomers have identified a possible new member of one of astronomy's strangest classes of objects: Odd radio circles (ORCs), enormous ring-like structures visible only at radio wavelengths. The newly discovered source, ...
The Haystack 37m Telescope has been a landmark in radio astronomy and radar studies of the solar system since its first light in 1964. Over the following four decades, it supported NASA's Apollo landings on the moon, made ...
