Radio jets from young stellar objects [PDF]

open access: yesThe Astronomy and Astrophysics Review, 2018
Jets and outflows are ubiquitous in the process of formation of stars since outflow is intimately associated with accretion. Free–free (thermal) radio continuum emission in the centimeter domain is associated with these jets.

Gas kinematics in powerful radio galaxies at z ~ 2: Energy supply from star formation, AGN, and radio jets [PDF]

open access: bronze, 2017
We compare the kinetic energy and momentum injection rates from intense star formation, bolometric AGN radiation, and radio jets with the kinetic energy and momentum observed in the warm ionized gas in 24 powerful radio galaxies at z~2.

Small-Scale Radio Jets [PDF]

open access: bronzeHighlights of Astronomy, 1983
Here I shall interpret ‘small-scale’ to mean a few kpc or less. Such jets occur over a wide range of emitted energies (e.g. 1039erg s–1 in M87, 1046 in 3C273) and we do not know if they are manifestations of the same basic phenomenon or whether Nature is fooling us in some way despite the morpholigicaI similarities. For the moment, it seems sensible to

Optical observations of radio jets [PDF]

open access: yesHighlights of Astronomy, 1980
Over the past several years a considerable body of evidence has accumulated, suggesting that extended radio sources are powered quasi-continuously from the nuclei of their parent galaxies. This view is supported by the recent discovery that several radio galaxies have narrow radio jets which connect their active nuclei with the large radio lobes and ...

Radio jets: properties, life and impact [PDF]

open access: greenProceedings 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 ...

Quasi-periodic oscillations of GHz-band polarization in a black hole [PDF]

open access: yesNature Communications
Relativistic jets from accreting black holes radiate non-thermal emission which is highly variable in different time scales. Previous studies on black holes of different mass scales, including supermassive and stellar-mass black holes, only report flux ...

Deceleration of SS433 radio jets [PDF]

open access: yes, 2013
The mildly relativistic jets of SS\,433 are believed to inflate the surrounding supernova remnant W\,50 depositing in its expansion possibly more than 99% of their kinetic energy (\cite[1998]{Dub98}).

Radio jets in NGC 4151

open access: yesThe Astrophysical Journal, 1982
The relationship between the radio and optical emissions from the nucleus of the Seyfert galaxy NGC 4151 is investigated by mapping the radio radiation from this source at wavelengths of 20 and 6 cm using the Very Large Array of the National Radio Astronomy Observatory.

ENVIRONMENT DENSITY OF A GIANT RADIO STRUCTURE FOR GALAXIES AND QUASARS WITH STEEP RADIO SPECTRA [PDF]

open access: yesRadio Physics and Radio Astronomy, 2021
Purpose: Estimate of the environment density of giant (with the linear size of about megaparsec) radio structures for galaxies and quasars with steep low-frequency spectra taken from the UTR-2 catalogue. Study of the cosmological evolution of environment
