Time-Dependent obscuration of a tidal disruption event candidate in the active galactic nucleus CSS100217
Ying Gu, Xiao Li, Xing-Qian Cheng +3
CSS100217 is considered a peculiar tidal disruption event (TDE) candidate occurring in an active galactic nucleus (AGN). Unlike typical TDEs, where the post-flare luminosity is equ…
FRB 20200428 and potentially associated hard X-ray bursts: Maser emission and synchrotron radiation of electrons in a weakly magnetized plasma?
Xiao Li, En-Wei Liang
The temporal and spatial coincidence between FRB 20200428 and hard peaks of the X-ray burst from SGR 1935+2154 suggests their potential association. We attributed them to the plasm…
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…
Repeating fast radio bursts from synchrotron maser radiation in localized plasma blobs: Application to FRB 20121102A
Xiao Li, Fen Lyu, Hai Ming Zhang +2
The radiation physics of repeating fast radio bursts (FRBs) remains enigmatic. Motivated by the observed narrow-banded emission spectrum and ambiguous fringe pattern of the spectra…
