A radio-jet-galaxy interaction in 3C 441 [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 Multi-wavelength imaging and spectroscopy of the z=0.708 radio galaxy 3C441 and a red aligned optical/infrared component are used to show that the most striking aspect of the radio-optical ``alignment effect'' in this object is due to the interaction of the radio jet with a companion galaxy in the same group or cluster.

Sources of Relativistic Jets in the Galaxy [PDF]
Annual Review of Astronomy and Astrophysics, 1999 ▪ Abstract Black holes of stellar mass and neutron stars in binary systems are first detected as hard X-ray sources using high-energy space telescopes. Relativistic jets in some of these compact sources are found by means of multiwavelength observations with ground-based telescopes.

The Jet-Cloud Interaction in 3CR Galaxies: Preliminary Results in Four Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe present preliminary results of the Gemini/GMOS longslit spectra for four radiogalaxies: 3C 135, 3C 180, 3C 234 and 3C 284. These objects are a subsample of a set of galaxies with noticeable extended structure selected from the HST/WFPC2 3CR Snapshot Survey, data taken with the filters F555W, F702W and narrow-ramp.

POWERFUL RELATIVISTIC JETS IN SPIRAL GALAXIES [PDF]
International Journal of Modern Physics: Conference Series, 2012 The discovery of high-energy (E > 100 MeV) γ rays from Narrow-Line Seyfert 1 Galaxies (γ-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (AGN). Although the jet emission is similar to that of blazars and radio galaxies, γ-NLS1s have some striking differences: relatively small masses (106-8 M⊙),

Unification of Radio Galaxies and their Accretion Jet Properties [PDF]
Journal of Astrophysics and Astronomy, 2011 We investigate the relation between black hole mass, M_bh, and jet power, Q_jet, for a sample of BL Lacs and radio quasars. We find that BL Lacs are separated from radio quasars by the FR I/II dividing line in M_bh-Q_jet plane, which strongly supports the unification scheme of FR I/BL Lac and FR II/radio quasar.

Rising jet-inflated bubbles in clusters of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract We conduct two-dimensional axisymmetric (referred to as 2.5D) hydrodynamical numerical simulations of bubble evolution in clusters of galaxies. We inflate bubbles using slow, massive jets with a wide opening angle, and follow their evolution as they rise through the intracluster medium.

Face‐on Dust Disks in Galaxies with Optical Jets
The Astrophysical Journal, 2000 The presence of optical synchrotron jets in radio galaxies is relatively rare. Here, we show that of the nearest five FR-I 3CR radio galaxies showing optical jets, {\it four} show evidence for almost circular, presumably face-on, dust disks. This is strong support for the two-fold idea that (\romannumeral1) jets emerge close to perpendicular to inner ...
