AT2019ijn: a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission
Hucheng Ding, Xinwen Shu, Luming Sun +9
We report the discovery of a peculiar optical transient, AT2019ijn, occurred in the nuclear region of a dwarf galaxy at z=0.273. It rises rapidly to peak at a luminosity of Mg=-21.…
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…
A central tidal disruption event candidate in high redshift quasar SDSS J000118.70+003314.0
Ying Gu, Xue-Guang Zhang, Xing-Qian Chen +2
We report a high-redshift () tidal disruption event (TDE) candidate in SDSS J000118.70+003314.0 (SDSS J0001), which is a quasar with apparent broad Mg~{\sc ii} emission li…
