Helical Magnetic Field in a Massive Protostellar Jet

The Astrophysical Journal Letters
Highly collimated outflows (jets) are observed across a wide range of astrophysical systems involving the accretion of material onto central objects, from supermassive black holes in active galaxies to proto-brown dwarfs and stellar-mass black holes ...

Varstrometry for Off-nucleus and Dual Sub-kiloparsec Active Galactic Nuclei (VODKA): Very Long Baseline Array Searches for Dual or Off-nucleus Quasars and Small-scale Jets

The Astrophysical Journal, 2023
Dual and off-nucleus active supermassive black holes are expected to be common in the hierarchical structure formation paradigm, but their identification at parsec scales remains a challenge due to strict angular resolution requirements.

Probing the Internal Structure of Magnetized, Relativistic Jets with Numerical Simulations

Galaxies, 2016
From an observational point of view, unveiling the physical processes behind the nature of the jets emanating from radio-loud AGN demands the resolution of the structure across the jet with the highest angular resolutions.

The Radio–X-Ray Correlation of High-redshift AGN: A Numerical Study of Inverse-Compton Scattering of the CMB Photons in Relativistic Jets

The Astrophysical Journal
Relativistic jets from active galactic nuclei are expected to exhibit strong redshift evolution in their radiative output due to the increasing energy density of the cosmic microwave background (CMB).

Jet-driven shocks and turbulence in radio-loud active galactic nuclei observed with JWST MIRI/MRS

Astronomy & Astrophysics
Jet–cloud interactions are a key manifestation of active galactic nucleus (AGN) feedback on nuclear scales, which is distinct from the large-scale radio-mode feedback that suppresses gas cooling in galaxy halos.

Radio Morphology of Gamma-Ray Sources: Double-lobed Radio Sources

The Astrophysical Journal
The extragalactic γ -ray sky is dominated by relativistic jets aligned to the observer’s line of sight, i.e., blazars. A few of their misaligned counterparts, e.g., radio galaxies, are also detected with the Fermi-Large Area Telescope (LAT), albeit in a ...
