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…
Simulations of interaction between outflow and surrounding broken power-law circumnuclear medium: implications for different radio light curves of TDEs
Xiangli Lei, Qingwen Wu, Chang Zhou +4
The complex radio light curves of tidal disruption events (TDEs) challenge our understanding of the properties of both the outflows and the circumnuclear medium (CNM) surrounding s…
Investigating the Circumnuclear Medium of Tidal Disruption Events with Radio Observations
Chang Zhou, Wei-Hua Lei, Xiangli Lei +3
Tidal disruption events (TDEs) are unique tools for investigating quiescent supermassive black hole (SMBH), accretion physics, and circumnuclear medium (CNM) environments. The CNM…
Minutes-long soft X-ray prompt emission from a compact object merger
An Li, Chen-Wei Wang, Niccolò Passaleva +75
Compact object mergers are multi-messenger sources and progenitors of some gamma-ray bursts (GRBs), primarily understood by gamma-ray observations, while poorly constrained in the…
Einstein Probe Discovery of an X-ray Flare from K-type Star PM J23221-0301
Guoying Zhao, WeiKang Zheng, Rong-Feng Shen +21
Stellar flares are an intense stellar activity that can significantly impact the atmospheric composition of the surrounding planets and even the possible existence of life. During…
A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
