AGN-Driven Biconical Outflows as the Origin of the Double-Peaked [O~{\sc iii}] doublet in SDSS J134733.36+121724.27
PeiZhen Cheng, XingQian Chen, GuiLin Liao +4
In this manuscript, we recheck the spectroscopic properties of SDSS J134733.36+121724.27 (4C+12.50), confirming the presence of the double-peaked [O~{\sc iii}]Å…
A candidate for True Type-2 AGN without hidden central BLRs Identified by central Tidal Disruption Event
Gu Ying, Zheng Qi, Cheng Peizheng +4
In this manuscript, through applications of TDE (tidal disruption event) expected variability properties, a potential candidate for True type-2 AGN without hidden central broad lin…
An improved Seyfert-LINER classification line in the [N~{\sc ii}] BPT diagram
PeiZhen Cheng, XingQian Chen, GuiLin Liao +3
In this manuscript, an improved Seyfert-LINER classification line (= S-L line) is proposed in the [N~{\sc ii}] BPT diagram, based on a sample of 47,968 low redshift narrow emission…
The orbital kinematics of kpc-scale dual-core systems with double-peaked narrow emission lines
XingQian Chen, Peizhen Cheng, Ying Gu +3
In this manuscript, based on SDSS photometry and spectroscopy, a method is proposed to test the hypothesis that the orbital kinematics of kpc-scale dual-core systems can lead to do…
