Classical and Relativistic Evolution of an Extra-Galactic Jet with Back-Reaction
Galaxies, 2018 We consider a turbulent jet that is moving in a Lane⁻Emden ( n = 5 ) medium. The conserved quantity is the energy flux, which allows finding, to first order, an analytical expression for the velocity and an approximate trajectory.

Radio sources in the Chandra Galactic Bulge Survey [PDF]
, 2012 We discuss radio sources in the Chandra Galactic Bulge Survey region. By cross-matching the X-ray sources in this field with the NRAO VLA Sky Survey archival data, we find 12 candidate matches.

Redshifts of CLASS Radio Sources [PDF]
The Astronomical Journal, 2000 Spectroscopic observations of a sample of 42 flat-spectrum radio sources from the Cosmic Lens All-Sky Survey (CLASS) have yielded a mean redshift of $ = 1.27$ with an RMS spread of 0.95, at a completeness level of 64%. The sample consists of sources with a 5-GHz flux density of 25-50 mJy, making it the faintest flat-spectrum radio sample for which the ...

Compact radio sources: Triggering and feedback
Astronomische Nachrichten, 2021 AbstractCSS/GPS objects represent a key stage in the evolution of powerful radio AGN in which the jets are expanding through the denser, kpc‐scale ISM in the host galaxies. Therefore, it is important both to understand how such radio AGN are triggered as galaxies evolve and to directly quantify the impact of the outflows induced by the jet‐cloud ...

Equipartition Jet Model for the Seyfert 1 Galaxy 3C120 [PDF]
Journal of Astronomy and Space Sciences, 2003 The motion of 3C120 Jet relative to the core is reasonably uniform and the VLBI scale jet connects outwards to a VLA ˜ 100 kpc scale. We measured the jet width variation from the center and found some indication of a power law which indicates the jet ...

An Atlas of Extragalactic Radio Sources [PDF]
Symposium - International Astronomical Union, 1996 Our Atlas of Extragalactic Radio Sources will present high-quality images of the nearer half of “3CRR”, the sample defined by Laing, Riley & Longair (1983). This is the best-studied complete sample of extragalactic radio sources. All 173 members have secure redshifts and most have been imaged in the radio at high resolution.

Radio loudness and classification for radio sources
Publications of the Astronomical Society of Japan, 2021 Abstract The extragalactic radio sources are divided into two subclasses (radio-loud and radio-quiet sources) in the literature using radio loudness (R), which is defined as the ratio of radio emission to optical emission, but the boundary R-value separating the two classes is different in various sources.
