OzSSy1: The Australian Southern Seyfert-1 Spectroscopic Atlas and Catalogue at z < 0.1
Neelesh Amrutha, Christian Wolf, Christopher A. Onken +3
We present a spectroscopic atlas of 887 broad-line active galactic nuclei (AGNs) in the Southern sky, spanning redshifts , declinations deg and Galactic latitudes $…
Optical Variability Structure Function of Low-Luminosity AGN using ATLAS Lightcurves
Ashley Hai Tung Tan, Christian Wolf, Neelesh Amrutha +3
The origin of the optical flux variability in active galactic nuclei (AGN) is largely unknown. Previous studies have correlated features of the variability structure function (SF)…
A catalogue of Type 2 active galactic nuclei in the 6dF Galaxy Survey
Sruthi Suresh, Wei Jeat Hon, Rachel L Webster +2
Active galactic nuclei (AGNs) are the compact, energetic central regions of galaxies, powered by supermassive black holes that accrete surrounding gas and dust. Their optical spect…
Discovering Changing-Look AGN in the 6dF Galaxy Survey using ATLAS Light curves
Neelesh Amrutha, Christian Wolf, Christopher A. Onken +4
Changing-Look Active Galactic Nuclei (CLAGN) are characterised by extreme variations in line emission over short timescales, mostly affecting broad H lines. While a few hundred…
Broad-line Active Galactic Nuclei in the 6dF Galaxy Survey
Wei Jeat Hon, Rachel Webster, Christian Wolf
The Six-degree Field Galaxy Survey (6dFGS) is a spectroscopic redshift survey of the Southern hemisphere completed in 2006. While it provides 136,304 spectra of mostly low-redshift…
