AT2019aalc: An obscured tidal disruption event candidate in an active galactic nucleus revealed by its first flare?
Ying Gu, Xiao Li, Xue-Guang Zhang +1
AT2019aalc is considered a repeating tidal disruption event (TDE) candidate occurring in an active galactic nucleus (AGN). In this paper, we highlight previously unnoticed but intr…
Signatures of Two Distinct Epochs of FRB 20240114A from January to August 2024 Based on its Energy and Waiting Time Analysis
Xiao Li, Ying Gu, En-Wei Liang
A comprehensive analysis of the energy and waiting time distributions of the bursts from FRB 20240114A detected by the Five-hundred-meter Aperture Spherical Radio Telescope between…
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…
