Recent models suggest approximately half of all accreting supermassive black holes (SMBHs; M _BH ≳ 10 ^5 M _⊙ ) are expected to undergo intense growth phases behind Compton-thick ( N _H > 1.5 × 10 ^24 cm ^−2 ) veils of obscuring gas. However,

A Uniformly Selected, Southern-Sky 6dF, Optical AGN Catalog

Autor: Yan-Ping Chen, Ingyin Zaw, Glennys R. Farrar, Sana Elgamal

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 6dF galaxy survey (Final Release of 6dFGS), a census of the Southern hemisphere. This work is an

We have constructed an all-sky catalog of optical AGNs with $z < 0.09$, based on optical spectroscopy, from the parent sample of galaxies in the 2MASS Redshift Survey (2MRS), a near-complete census of the nearby universe. Our catalog consists of 1929

The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) is a targeted survey probing the narrow-line regions (NLRs) of a representative sample of \(\sim \) 140 nearby (z < 0. 02) Seyfert galaxies by means of optical integral field spect
