Observations of the gamma-ray emitting narrow-line Seyfert 1, SBS 0846+513, and its host galaxy
Timothy S. Hamilton, Marco Berton, Sonia Antón +9
The gamma-ray emitting galaxy SBS 0846+513 has been classified as a Narrow-Line Seyfert 1 from its spectroscopy, and on that basis it was thought likely to have a small central bla…
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…
Near-infrared morphologies of the host galaxies of narrow-line Seyfert 1 galaxies
Emilia Järvelä, Anne Lähteenmäki, Marco Berton
We present -band near-infrared (NIR) imaging of the host galaxies of nine narrow-line Seyfert 1 galaxies (NLS1). Based on high-frequency radio observations at 37~GHz, seven of t…
Large-scale environments of narrow-line Seyfert 1 galaxies
Emilia Järvelä, Anne Lähteenmäki, Heidi Lietzen +3
Studying large-scale environments of narrow-line Seyfert 1 (NLS1) galaxies gives a new perspective on their properties, particularly their radio loudness. The large-scale environme…
Kiloparsec-scale emission in the narrow-line Seyfert 1 galaxy Mrk 783
E. Congiu, M. Berton, M. Giroletti +12
We present the first results of a radio survey of 79 narrow-line Seyfert 1 (NLS1) carried out with the Karl G. Jansky Very Large Array (JVLA) at 5 GHz in A configuration aimed at s…
Narrow-line Seyfert 1 galaxies - rebels of the AGN family
Emilia Järvelä, Anne Lähteenmäki
Narrow-line Seyfert 1 galaxies, with their extreme properties, defy our current knowledge of active galactic nuclei and relativistic jet systems. They excite, and might help us ans…
