Simulations of Precessing Jets and the Formation of X-shaped Radio Galaxies
Jet precession is sometimes invoked to explain asymmetries in radio galaxy (RG) jets and “X/S/Z-shaped” RGs, caused by the presence of a binary black hole companion to the source active galactic nucleus or by accretion instabilities.

High-sensitivity VLA observations of M51 at 6 cm wavelength with sub-arcsecond resolution have resolved the southern extra-nuclear cloud identified by Ford et al. [ApJ, 293, 132 (1985)]. These observations reveal a short (3-4"), sinuous jetlike feature connecting the weak nuclear radio source to a bright arcuate ridge of radio emission that dominates ...

Ionized-gas Kinematics Along the Large-scale Radio Jets in Type-2 AGNs [PDF]
To investigate the connection between radioactivity and active galactic nucleus (AGN) outflows, we present a study of ionized-gas kinematics based on an [O iii] λ5007 emission line along the large-scale radio jet for six radio AGNs.

Since thermal radio jets can be observed with subarsecond angular resolution and are unaffected by dust absorption, they provide a useful tool to study collimated outflows very close to the young stars that produce them. Here, I review recent results on this area, giving emphasis to the study of thermal jets in the case of the quadrupolar outflows in ...

ACCELERATION OF COMPACT RADIO JETS ON SUB-PARSEC SCALES [PDF]
Jets of compact radio sources are highly relativistic and Doppler boosted, making studies of their intrinsic properties difficult. Observed brightness temperatures can be used to study the intrinsic physical properties of relativistic jets, and constrain

Hydromagnetic flows from accretion discs and the production of radio jets
Summary. We examine the possibility that energy and angular momentum are removed magnetically from accretion discs, by field lines that leave the disc surface and extend to large distances.

Radio Jets Clearing the Way Through a Galaxy: Watching Feedback in Action [PDF]
Pushy Black Hole The giant black holes that sit at the centers of most galaxies influence the way galaxies evolve in poorly understood ways. Morganti et al. (p. 1082; see the Perspective by McNamara) have acquired high-resolution radio images of a galaxy

The discovery of 3C 273 in 1963, and the emergence of the Kerr solution shortly thereafter, precipitated the current era in astrophysics focused on using black holes to explain active galactic nuclei (AGN).

Radio Jets in Young Stellar Objects with the SKA [PDF]
Jets are ubiquitous in the star-forming process since accretion is intimately associated with outflow. Weak free-free continuum emission in the centimeter domain is associated with these jets.
