Narrow-line Seyfert 1 galaxies with absorbed jets -- insights from radio spectral index maps
Emilia Järvelä, Marco Berton, Luca Crepaldi
Narrow-line Seyfert 1 (NLS1) galaxies are active galactic nuclei (AGN) believed to be in the early stages of their evolution. A fraction of them have been found to host relativisti…
Hunting for the nature of the enigmatic narrow-line Seyfert 1 galaxy PKS 2004-447
M. Berton, G. Peluso, P. Marziani +19
Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that, in some cases, can harbor powerful relativistic jets. One of them, PKS 2004-447, shows gamma…
The Radio Structure of the Narrow-Line Seyfert 1 Mrk 783 with VLBA and e-MERLIN
E. Congiu, P. Kharb, A. Tarchi +9
In this paper, we present the analysis of new radio and optical observations of the narrow-line Seyfert 1 galaxy Mrk 783. 1.6 GHz observations performed with the e-MERLIN interfero…
The Energetics of Launching the Most Powerful Jets in Quasars: A Study of 3C82
Brian Punsly, Gary J. Hill, Paola Marziani +5
3C 82 at a redshift of 2.87 is the most distant 3C (Third Cambridge Catalogue) quasar. Thus, it is a strong candidate to have the most luminous radio lobes in the Universe. 3C 82 b…
Radio morphology of southern narrow-line Seyfert 1 galaxies with Very Large Array observations
S. Chen, E. Jarvela, L. Crepaldi +8
We present the results of new radio observations carried out with the Karl G. Jansky Very Large Array C-configuration at 5.5 GHz for a sample of southern narrow-line Seyfert 1 gala…
Absorbed relativistic jets in radio-quiet narrow-line Seyfert 1 galaxies
M. Berton, E. Järvelä, L. Crepaldi +6
Narrow-line Seyfert 1 (NLS1) galaxies are peculiar active galactic nuclei (AGN). Most of them do not show strong radio emission, but recently seven radio-quiet (or -silent) NLS1s h…
