Similar ratios of rise timescale to decline timescale of optical light curves in common tidal disruption events

Zhang XueGuang

Totally similar physical process in tidal disruption events (TDEs) basically indicates that there should be potential parameter to distinguish variability properties of TDEs from t…

Double tidal disruption events in the changing-look AGN Mrk1018

Zhang XueGuang

Tidal disruption events (TDEs) as excellent beacons to black hole (BH) accreting systems have been studied for more than five decades with a single star tidally disrupted by a cent…

A normal broad line AGN SDSS J1617+0638 as the host galaxy of a central tidal disruption event

Zhang XueGuang

In this manuscript, strong clues are reported to support the normal broad line AGN SDSS J1617+0638 as the host galaxy harboring a central tidal disruption event (TDE). Through the…

SDSS J222428.53+261423.2: unique emission lines properties unveil a sub-kiloparsec dual AGN candidate

Qi Zheng, XueGuang Zhang, QiRong Yuan +2

In this paper, we presented a detailed analysis of the Sloan Digital Sky Survey optical spectrum of a new sub-kpc scale dual AGN candidate SDSS J222428.53+261423.2 (=SDSS J2224). T…

A candidate for central tidal disruption event in the broad line AGN SDSS J1605 with double-peaked broad H

XueGuang Zhang

In this letter, motivated by double-peaked broad Balmer emission lines probably related to tidal disruption events (TDEs), a potential TDE candidate is reported in SDSS J160536+134…

Modeling the flare in NGC 1097 from 1991 to 2004 as a tidal disruption event

XueGuang Zhang

In the Letter, interesting evidence is reported to support a central tidal disruption event (TDE) in the known AGN NGC 1097. Considering the motivations of TDE as one probable orig…
