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.
New Curtin University-led research has used a radio telescope that spans Earth to snap images that measure the immense power of jets from black holes, confirming scientists' theories of how black holes help shape the structure ...

Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as "triple-double" radio galaxies (TDRGs). Located ...
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious ...
An international collaboration using the Low Frequency Array (LOFAR) has published an exceptionally detailed radio sky map, revealing 13.7 million cosmic sources and delivering the most complete census yet of actively growing ...

An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended radio jet of this galaxy. ...
A supermassive black hole with a case of cosmic indigestion has been burping out the remains of a shredded star for four years—and it's still going strong, new research led by a University of Oregon astrophysicist shows.

When astronomers look out into the cosmos, they see supermassive black holes (SMBH) in two different states. In one state, they're dormant. They're actively accreting only a tiny amount of matter and emit only faint, weak ...

Some galaxies eject powerful streams of charged particles—jets—from their centers into space. The prominent jet of Messier 87 (M87) in the constellation Virgo is visible over distances of 3,000 light-years and can be observed ...

An international team of astronomers has analyzed the data from long-term multiwavelength monitoring of a distant blazar known as OP 313. Results of the new study, published January 18 on the arXiv preprint server, shed more ...
Astronomers at the University of Warwick have discovered that black holes don't just consume matter—they manage it, choosing whether to blast it into space as high-speed jets or sweep it away in vast winds.
