Parsec-Scale Jets and Tori in Seyfert Galaxies [PDF]
Symposium - International Astronomical Union, 2001 What causes the dichotomy between very powerful and very weak radio emission from AGNs? Perhaps the engines are the same but the jets get disrupted by dense ISM in radio-quiet objects, or else the engines are intrinsically different with jet power scaling with, say, black hole spin.

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⊙),

Face‐on Dust Disks in Galaxies with Optical Jets [PDF]
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 ...

Heating groups and clusters of galaxies: The role of AGN jets [PDF]
, 2004 X-ray observations of groups and clusters of galaxies show that the Intra-Cluster Medium (ICM) in their cores is hotter than expected from cosmological numerical simulations of cluster formation which include star formation, radiative cooling and SN ...

ROTATION MEASURES ACROSS PARSEC-SCALE JETS OF FANAROFF-RILEY TYPE I RADIO GALAXIES [PDF]
, 2009 We present the results of a parsec-scale polarization study of three FRI radio galaxies—3C66B, 3C78, and 3C264—obtained with Very Long Baseline Interferometry at 5, 8, and 15 GHz.

Jets in radio galaxies and quasars: an observational perspective [PDF]
Journal of astrophysics and astronomy, 2022 This article gives a brief historical introduction and reviews our current understanding of jets in radio galaxies and quasars from an observational perspective, with an emphasis on observations at radio wavelengths. Recent results on the Fanaroff–Riley (

Which AGN jets quench star formation in massive galaxies? [PDF]
Monthly notices of the Royal Astronomical Society, 2021 Without additional heating, radiative cooling of the halo gas of massive galaxies (Milky Way-mass and above) produces cold gas or stars exceeding that observed.
