Abnormal Nitrogen Abundance in the X-ray Spectrum of Quasi-periodically Erupting Source AT2019wzc
Tao Wu, Xinwen Shu, Luming Sun +3
Quasi-periodic eruptions (QPEs) are rapid, recurring soft X-ray bursts, whose nature is still in dispute. A compelling case of QPEs has emerged in the slowly evolving optical trans…
Tidal Disruption Events with the SKA
T. An, A. J. Goodwin, J. C. A. Miller-Jones +3
The paper outlines how the Square Kilometre Array’s sensitivity, wide frequency coverage, and VLBI capabilities will enable large‑scale radio studies of tidal disruption events, im…
Radio and X-ray flux rebrightening six years after outburst in a partially-obscured extreme changing-look AGN
Tianyao Zhou, Xinwen Shu, Lei Yang +14
The paper reports multi‑year observations of the partially obscured AGN SDSS J1548+2208, revealing sustained high mid‑infrared and hard X‑ray fluxes and a late‑time radio rebrighte…
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.…
Numerical Studies on the Radio Afterglows in TDE: Bow Shock
Guobin Mou, Xinwen Shu
The origin of radio afterglows or delayed radio flares in tidal disruption events (TDEs) is not fully understood. They could be generated either by a forward shock propagating into…
Exploring Tidal Disruption Events with SKA and VLBI: Unveiling the Mystery of Black Hole Feeding and Outflows
Xinwen Shu, Guobin Mou, Tao An +8
Tidal disruption events (TDEs) probe the birth and evolution of black hole accretion flows and jets on human timescales. Radio emission traces shocks and outflows from thermal TDEs…
