Dorado and its member galaxies. Ha imaging of the group backbone
R. Rampazzo, S. Ciroi, P. Mazzei +9
ABRIDGED: Dorado is a nearby, rich and clumpy galaxy group that extends for several degrees in the Southern Hemisphere. For the first time, we map the Ha distribution as a possible…
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…
SDSS J211852.96-073227.5: The first non-local, interacting, late-type intermediate Seyfert galaxy with relativistic jets
Emilia Järvelä, Marco Berton, Stefano Ciroi +3
It has been often suggested that a tangible relation exists between relativistic jets in active galactic nuclei (AGN) and the morphology of their host galaxies. In particular, rela…
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…
Line shapes in narrow-line Seyfert 1 galaxies: a tracer of physical properties?
M. Berton, I. Björklund, A. Lähteenmäki +4
Line profiles can provide fundamental information on the physics of active galactic nuclei (AGN). In the case of narrow-line Seyfert 1 galaxies (NLS1s) this is of particular import…
