Radio jets: Properties, life and impact [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractOur view of the properties of extragalactic radio jets and the impact they have on the host galaxy has expanded in the recent years. This has been possible thanks to the data from new or upgraded radio telescopes. This review briefly summarises the current status of the field and describes some of the exciting recent results and the surprises ...

Jets in FR0 radio galaxies [Dataset]
, 2023 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 ...

Radio Jet and Lobe of 3C273 [PDF]
Symposium - International Astronomical Union, 1986 The ‘superluminal’ motion observed in the cores of radio sources such as 3C273 is now accepted as evidence of relativistic motion within a few parsecs of the centre, but it is less clear whether such speeds persist out to kiloparsec scales. The one-sidedness of such sources is often cited as evidence of relativistic Doppler beaming, but could equally ...

The Astronomical Journal, 1992 High-sensitivity VLA observations of M51 at 6 cm wavelength with sub-arcsecond resolution have resolved the southern extra-nuclear cloud identified by Ford et al. [ApJ, 293, 132 (1985)]. These observations reveal a short (3-4"), sinuous jetlike feature connecting the weak nuclear radio source to a bright arcuate ridge of radio emission that dominates ...

Galaxies, 2021 The radiative and jet power in active galactic nuclei is generated by accretion of material on to supermassive galactic-centre black holes. For quasars, where the radiative power is by definition very high, objects with high radio luminosities form 10 ...

Discovery of synchrotron emission from a YSO jet
EPJ Web of Conferences, 2013 Synchrotron emission at radio wavelengths is commonly found in relativistic jets from active galactic nuclei (AGNs) and microquasars and allows the study of the magnetic field in these kind of jets.

Simulations of Precessing Jets and the Formation of X-shaped Radio Galaxies
The Astrophysical Journal, 2023 Jet precession is sometimes invoked to explain asymmetries in radio galaxy (RG) jets and “X/S/Z-shaped” RGs, caused by the presence of a binary black hole companion to the source active galactic nucleus or by accretion instabilities.

Spectral ageing in the lobes of FR-II radio galaxies: new methods of analysis for broad-band radio data [PDF]
, 2013 The broad-bandwidth capabilities of next generation telescopes such as the Jansky Very Large Array (JVLA) mean that the spectrum of any given source varies significantly within the bandwidth of any given observation.

Interaction of jets with the ISM of radio galaxies [PDF]
Astrophysics and Space Science, 2007 We present three dimensional simulations of the interaction of a light hypersonic jet with an inhomogeneous thermal and turbulently supported disk in an elliptical galaxy, including Radio and multi-band X-ray visualisations. These simulations are applicable to the GPS/CSS phase of some extragalactic radio sources. We identify four generic phases in the

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS
Solar-Terrestrial Physics, 2020 We have investigated the cause of three “isolated” negative radio bursts recorded one after another at several frequencies in the 1–17 GHz range at the Nobeyama Radio Observatory, Ussuriysk Astrophysical Observatory, and Learmonth Solar Observatory on ...
