The many lives of active galactic nuclei–II: The formation and evolution of radio jets and their impact on galaxy evolution [PDF]
We describe new efforts to model radio active galactic nuclei (AGN) in a cosmological context using the Semi-Analytic Galaxy Evolution (SAGE) semi-analytic galaxy model.

Gas kinematics in powerful radio galaxies at z ~ 2: Energy supply from star formation, AGN, and radio jets [PDF]
We compare the kinetic energy and momentum injection rates from intense star formation, bolometric AGN radiation, and radio jets with the kinetic energy and momentum observed in the warm ionized gas in 24 powerful radio galaxies at z~2.

A candidate dual AGN in a double-peaked emission-line galaxy with precessing radio jets [PDF]
We present high resolution radio continuum observations with the Karl G. Jansky Very Large Array at 6, 8.5, 11.5 and 15 GHz of the double-peaked emission-line galaxy 2MASXJ12032061+1319316.

Relation between winds and jets in radio-loud AGN [PDF]
We have investigated the relation between the two modes of outflow (wind and jet) in radio-loud active galactic nuclei (AGN). For this study we have carried out a systematic and homogeneous analysis of XMM-Newton spectra of a sample of 16 suitable radio ...

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.

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.

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).

A new list of extra-galactic radio jets [PDF]
A catalogue of extra-galactic jets is very useful both in observational and theoretical studies of active galaxies. With the use of new powerful radio instruments, the detailed structures of very compact or weak radio sources are investigated observationally and many new radio jets are detected.

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
