Jet propagation velocity and environment density of giant radio sources with steep radio spectrum [PDF]
, 2018 Before we have determined that giant radio structure is typical for steep-spectrum sources detected with Ukrainian T-shaped Radio Telescope of model 2 (UTR-2). To estimate the jet propagation velocity and environment density of giant radio sources we consider the sample of galaxies and quasars with steep radio spectrum compiled from two regions of UTR ...

Jet-Induced Feedback in the [O III] Lines of Early Evolution Stage Active Galactic Nuclei
Universe, 2021 It is well known that active galactic nuclei (AGN) show various forms of interaction with their host galaxy, in a number of phenomena generally called AGN feedback.

Particle content, radio-galaxy morphology and jet power: all radio-loud AGN are not equal [PDF]
, 2018 Ongoing and future radio surveys aim to trace the evolution of black hole growth and feedback from active galactic nuclei (AGN) throughout cosmic time; however, there remain major uncertainties in translating radio luminosity functions into a reliable assessment of the energy input as a function of galaxy and/or dark matter halo mass.

Unveiling the Small-scale Jets in the Rapidly Growing Supermassive Black Hole IZw1
The Astrophysical JournalAccretion of black holes at near-Eddington or super-Eddington rates represents the most powerful episode driving black hole growth, potentially occurring across various types of objects.

Probing the Internal Structure of Magnetized, Relativistic Jets with Numerical Simulations
Galaxies, 2016 From an observational point of view, unveiling the physical processes behind the nature of the jets emanating from radio-loud AGN demands the resolution of the structure across the jet with the highest angular resolutions.

Evidence that powerful radio jets have a profound influence on the evolution of galaxies [PDF]
, 2004 The relationships between supermassive black holes and the properties of their associated dark-matter halos imply that outflows from accreting black holes provide a feedback mechanism regulating galaxy formation. Accreting black holes with weak or undetectable radio jets (radio-quiet quasars) outnumber those with powerful jets (radio-loud quasars) by a

THE RELATION BETWEEN AGN GAMMA-RAY EMISSION AND PARSEC-SCALE RADIO JETS [PDF]
, 2009 We have compared the radio emission from a sample of parsec-scale active galactic nucleus (AGN) jets as measured by the VLBA at 15 GHz, with their associated γ-ray properties that are reported in the Fermi Large Area Telescope (LAT) three month bright ...

A survey of extended radio jets in AGN with Chandra and HST: First Results [PDF]
, 2002 We present the first results from an X-ray and optical survey of a sample of AGN radio jets with Chandra and HST. We focus here on the first six sources observed at X-rays, in four of which a bright X-ray jet was detected for the first time. In three out
