Southern-sky optical AGN catalog from 6dFGS sp.
Listed in IVOA Registry (Virtual Observatory)
We have constructed a catalog of active galactic nuclei (AGNs) with z<0.13, based on optical spectroscopy, from the parent sample of galaxies in the Six-Degree Field (6dF) galaxy survey (Final Release of 6dFGS), a census of the Southern Hemisphere.
Description
This work is an extension of our all-sky AGN catalog in Zaw+ (ZCF; 2019, J/ApJ/872/134). The ZCF is based on 43533 galaxies with Ks<=11.75 (z<=0.09) in the Two Micron All-Sky Survey (2MASS) Redshift Survey (2MRS).
The parent catalog of this work, the 6dF catalog, consists of 136304 publicly available digital spectra for 125071 galaxies with decl. <=0{deg} and Ks<=12.65 (median z=0.053). Our AGN catalog consists of 3109 broadline AGNs and 12156 narrowline AGNs which satisfy the 2003 criteria, of which 3865 also satisfy the 2001 criteria. We also provide emission-line widths, fluxes, flux errors, and signal-to-noise ratios of all the galaxies in our spectroscopic sample, allowing users to customize the selection criteria.

In addition, we provide the AGN likelihood for the rest of galaxies based on the availability and quality of their spectra. These likelihood values can be used for rigorous statistical analyses.
