The relationship between the radio core-dominance parameter and spectral index in different classes of extragalactic radio sources (III)
Zhi-Yuan Pei, Jun-Hui Fan, Denis Bastieri +3
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…
Radio core dominance of Fermi-LAT selected AGNs
Zhi-Yuan Pei, Jun-Hui Fan, Denis Bastieri +2
Aims. We present a sample of 4388 AGNs with available radio core-dominance parameters defined as the ratio of the core flux densities to extended ones, namely, R = Score/Sext., whi…

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…
