Interstellar dust as a dynamic environment
G. La Mura, G. Mulas, M. A. Iatì +3
In spite of accounting for only a small fraction of the mass of the Interstellar Medium (ISM), dust plays a primary role in many physical and chemical processes in the Universe. It…
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…
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…
A catalog of narrow-line Seyfert 1 galaxies in the southern hemisphere
S. Chen, M. Berton, G. La Mura +7
We present a new accurate sample of narrow-line Seyfert 1 galaxies (NLS1s) in the southern hemisphere from the Six-degree Field Galaxy Survey (6dFGS). Based on the optical spectral…
Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies
G. De Rosa, M. M. Fausnaugh, C. J. Grier +99
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…
The interacting late-type host galaxy of the radio-loud narrow-line Seyfert 1 IRAS 20181-2244
M. Berton, E. Congiu, S. Ciroi +15
Narrow-line Seyfert 1 galaxies (NLS1s) are a class of active galactic nuclei (AGN) which are known to be one of the few sources of rays, which originate in a relativistic beame…
Radio-emitting narrow-line Seyfert 1 galaxies in the JVLA perspective
M. Berton, E. Congiu, E. Järvelä +14
We report the first results of a survey on 74 narrow-line Seyfert 1 galaxies (NLS1s) carried out in 2015 with the Karl G. Jansky Very Large Array (JVLA) at 5 GHz in A-configuration…
Models of emission line profiles and spectral energy distributions to characterize the multi-frequency properties of active galactic nuclei
Giovanni La Mura, Marco Berton, Sina Chen +7
The spectra of Active Galactic Nuclei (AGNs) are often characterized by a wealth of emission lines with different profiles and intensity ratios that led to a complicated classifica…
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…
Unveiling the parent population of beamed narrow-line Seyfert 1s
M. Berton, L. Foschini, S. Ciroi +11
Narrow-line Seyfert 1 galaxies (NLS1s) are active galactic nuclei (AGN) recently identified as a new class of -ray sources. The high energy emission is explained by the presence…
