Infrared Echoes of Precessing Tidal Disruption Events
Hong-Zhou Wu, Shao-Yu Fu, Wen-Long Xu +2
A tidal disruption event (TDE) occurs when a star is torn apart by a supermassive black hole. The resulting UV/optical flare irradiates parsec-scale dust, producing delayed mid-inf…
A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However,…
Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
Propagation of Precessing Jet in Envelope of Tidal Disruption Events
Hao-Yu Yuan, Hong-Zhou Wu, Wei-Hua Lei
It is likely that the disk of a tidal disruption event (TDE) is misaligned with respect to the equatorial plane of the spinning supermassive black hole (SMBH), since the initial st…
