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…
The Impact of Elliptical Broad-Line Regions on Reverberation-Based Black Hole Mass Estimates
Jiancheng Wu, Haicheng Feng, Qingwen Wu +1
The virial factor is critical for accurate supermassive black hole (SMBH) mass measurements using reverberation mapping (RM) and the radius--luminosity (--) relation, yet…
Formation of dust clumps in the torus of active galactic nuclei
Xinwu Cao, Renyue Cen, Qingwen Wu +1
The putative dusty torus is a key ingredient of the unification scheme of active galactic nuclei (AGN), but its origin remains a mystery. Here we put forward a new physical model t…
Simulations of Tidal Disruption of Supernova in Galaxy Nuclear Region: A Novel Model for Ambiguous Nuclear Transients
Xiangli Lei, Qingwen Wu, Ya-Ping Li +1
An increasing number of ambiguous nuclear transients, including some extreme nuclear transients with very shallow light-curve declines and weak AGN activity in their host galaxies,…
Simulation of Binary-Single Interactions in AGN Disks II: Merger Probability of Binary Black Holes during Chaotic Triple Process
Mengye Wang, Qingwen Wu, Yiqiu Ma
Stellar-mass binary black hole\,(BBH) mergers resulting from binary-single interactions\,(BSIs) in active galactic nucleus\,(AGN) disks are a potential source of gravitational wave…
The Role of Population III Star Tidal Disruption Events in Black Hole Growth at the Cosmic Dawn
Zijian Wang, Yiqiu Ma, Yuxuan Li +3
The discovery of supermassive black holes (SMBHs) at high redshifts has intensified efforts to understand their early formation and rapid growth during the cosmic dawn. Using a sem…
