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…
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…
A correlation between [O III] line property and X-ray spectral complexity in narrow-line Seyfert 1 galaxies?
S. Chen, G. La Mura, M. Berton +7
We present a detailed study of 11 narrow-line Seyfert 1 galaxies (NLS1s) from the Six-degree Field Galaxy Survey (6dFGS) that both have optical and X-ray spectroscopic observations…
The link between X-ray complexity and optical lines in NLS1s
A. Vietri, M. Berton, S. Ciroi +8
Narrow-line Seyfert 1 galaxies (NLS1s) are a subclass of active galactic nuclei (AGN). It is often believed that these AGN have small black hole mass, which is responsible for the…
