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…
Models of Optical Emission Lines To Investigate Narrow-Line Seyfert 1 Galaxies in Spectroscopic Databases
G. La Mura, D. Bastieri, M. Berton +6
Thanks to the execution of extensive spectroscopic surveys that have covered large fractions of the sky down to magnitudes as faint as , it has been possible to ident…
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…
Optical observations of "hot" novae returning to quiescence
P. Zemko, S. Ciroi, M. Orio +10
We have monitored the return to quiescence of novae previously observed in outburst as supersoft X-ray sources, with optical photometry of the intermediate polar (IP) V4743 Sgr and…
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…
