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.
A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered a strange jet protruding ...

Scientists have long been aware of the massive elliptical galaxy, M87. The galaxy was first observed in the late 18th century by Charles Messier, who cataloged objects in the sky specifically to avoid them when looking for ...
The sharpest images of the universe are created when radio telescopes around the world work together. For the first time, the world's largest network of radio telescopes, EVN, has observed together with South Africa's MeerKAT, ...

Astronomers have conducted very long baseline Interferometry (VLBI) observations of an active galaxy known as Markarian 110. As a result, they detected a relativistic jet in this galaxy. The finding was reported in a research ...
Using the Very Long Baseline Array (VLBA), European astronomers have carried out multi-wavelength radio observations of a radio galaxy designated 3C 111. Results of the observational campaign, published March 24 on the arXiv ...
One of the most powerful objects in the universe is a radio quasar—a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational pull, or burn up from the ...

Using the Australia Telescope Compact Array (ATCA), astronomers have performed high-resolution observations of a nearby pulsar wind nebula in the supernova remnant G11.2−0.3. Results of the observational campaign, published ...
From decades of astronomical observations, scientists know that most galaxies contain massive black holes at their centers. The gas and dust falling into these black holes liberates an enormous amount of energy as a result ...
