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 We performed $J$-band observations of the host galaxies of nine narrow-line Seyfert 1 galaxies (NLS1). Seven of these sources have been detected at 37 GHz and are likely to host relativistic jets. Host galaxy properties of the jetted NLS1 galaxies are not yet well known, and investigating them is essential to get more insight into their characteristics

Jet Directions in Seyfert Galaxies [PDF]
The Astrophysical Journal, 2000 We present the study of the relative angle between the accretion disk (or radio jet) and the galaxy disk for a sample of Seyfert galaxies selected from a mostly isotropic property, the 60$ $m flux. For each galaxy we have a pair of points ($i$,$ $), which are the inclination of the galaxy relative to the line of sight and the angle between the jet ...

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.

CCD observations of galaxies with radio jets [PDF]
Symposium - International Astronomical Union, 1986 We present preliminary results of a CCD survey of nearby (z<0.1) northern galaxies which have well defined radio jets. Our main objectives are to: 1) detect - or put constraints to - the presence of optical jets in these galaxies, 2) obtain high dynamic range maps of known optical jets, and 3) make a detailed comparison of our results with those ...

Astronomy & Astrophysics, 2022 Narrow-line Seyfert 1 (NLS1) galaxies are unevolved active galactic nuclei (AGNs) that exist predominantly in spiral galaxies. However, mostly due to the small number of sources studied, it has been under debate whether also the hosts of jetted NLS1 galaxies, a particular subclass of these sources hosting a relativistic jet, are disk-like or elliptical,

Superdiscs in radio galaxies: jet–wind interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Taking a clue from their sharp-edged (strip-like) morphology observed in several cases, a new mechanism is proposed for the formation of the emission gaps seen between the radio lobes of many powerful extragalactic double radio sources. Canonical understanding of the radio gaps invokes either blocking of the back-flowing lobe plasma by the denser ...

Jet‐triggered star formation in young radio galaxies [PDF]
Astronomische Nachrichten, 2021 AbstractEmission in the ultraviolet continuum is a salient signature of the hot, massive, and consequently short‐lived, stellar population that traces recent or ongoing star formation. With the aim of mapping star forming regions and morphologically separating the generic star formation from that associated with the galaxy‐scale jet activity, we ...
