Broad-line AGN in 6dF Galaxy Survey
Listed in IVOA Registry (Virtual Observatory)
The Six-degree Field Galaxy Survey (6dFGS) is a spectroscopic redshift survey of the Southern hemisphere completed in 2006.
Description
While it provides 136,304 spectra of mostly low-redshift galaxies, a large and reliable catalogue of Active Galactic Nuclei (AGN) that are selected based on spectral signatures is still lacking. In this work, we present an extensive list of verified broad emission-line AGN in the 6dFGS sample.
We visually confirm the AGN nature of all spectra, and disentangle fibre cross-talk to remove bogus AGN. The final catalogue contains 2,513 unique broad-line AGN with a median redshift of 0.207, of which 891 are identified for the first time. A flux-limited subsample contains 665 AGN to a K-band magnitude of 13.

This new sample adds to the list of known low-luminosity AGN in the Southern hemisphere and thus provides a basis for investigations of low-redshift AGN with the upcoming Vera C. Rubin Observatory.
