The relationship between the radio core-dominance parameter and spectral index in different classes of extragalactic radio sources (II)
Zhi-Yuan Pei, Jun-Hui Fan, Denis Bastieri +2
Active galactic nuclei (AGNs) can be divided into two major classes, namely radio loud and radio quiet AGNs. A small subset of the radio-loud AGNs is called blazars, which are beli…
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…
Probing narrow-line Seyfert 1 galaxies in the southern hemisphere
S. Chen, M. Berton, G. La Mura +7
We present a new accurate catalog of narrow-line Seyfert 1 galaxies (NLS1s) in the southern hemisphere from the Six-degree Field Galaxy Survey (6dFGS) final data release, which is…
