On the efficiency of jet production in radio galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 The mechanisms that produce and power relativistic jets are fundamental open questions in black hole (BH) astrophysics. In order to constrain these mechanisms, we analyze the energy efficiency of jet production 'eta' based on archival Chandra observations of 27 nearby, low-luminosity active galactic nuclei. We obtain 'eta' as the ratio of the jet power,

Efficient Long-range Active Galactic Nuclei (AGNs) Feedback Affects the Low-redshift Lyα Forest
The Astrophysical Journal Letters, 2023 Active galactic nuclei (AGNs) feedback models are generally calibrated to reproduce galaxy observables such as the stellar mass function and the bimodality in galaxy colors.

Astronomy & Astrophysics, 2023 Context.The local radio-loud AGN population is dominated by compact sources named FR0s. These sources show features, for example the host type, the mass of the supermassive black hole (SMBH), and the multi-band nuclear characteristics, that are similar to those of FRI radio galaxies.

The Multiwavelength Environment of Second Bologna Catalog Sources
The Astrophysical Journal Supplement Series, 2023 We present the first results of the Chandra Cool Targets (CCT) survey of the Second Bologna Catalog (B2CAT) of powerful radio sources, aimed at investigating the extended X-ray emission surrounding these sources.

Host galaxies of jetted narrow-line Seyfert 1 galaxies [PDF]
Proceedings of Revisiting narrow-line Seyfert 1 galaxies and their place in the Universe — PoS(NLS1-2018), 2018 Host galaxy morphology studies of jetted narrow-line Seyfert 1 galaxies (NLS1) are scarce; so far only three of them have been investigated in detail. Though all three are hosted by late-type galaxies the sample size is too small to establish a preferred host galaxy type for jetted NLS1 sources; increasing the sample size is crucial to achieve ...

The Conference Blazars through Sharp Multi-Wavelength Eyes
Galaxies, 2016 Blazars are active, galactic nuclei with jets of magnetized, high-energy plasma that flow outward from the center of the host galaxy at near-light speeds.[...]

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.
