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…
Accretion-Mode Transition: The Driver Behind Spectral Changes in Changing-Look AGNs
Pengyuan Han, Huaiyuan Lu, Bing Lyu +2
The physical origin of optical changing-look AGNs (CLAGNs), characterized by the appearance or disappearance of broad emission lines, is thought to be mainly driven by the variatio…
Composite spectrum of Little Red Dot from a standard inner disk and an unstable outer disk
Chenxuan Zhang, Qingwen Wu, Xiao Fan +6
James Webb Space Telescope (JWST) has revealed a new class of high-redshift, very red, compact broad-line sources, termed as "little red dots" (LRDs). The physical mechanism drivin…
Simulation of Binary-Single Interactions in AGN Disk I: Gas-Enhanced Binary Orbital Hardening
Mengye Wang, Yiqiu Ma, Hui Li +4
Stellar-mass binary black hole\,(BBH) mergers within the accretion disks of active galactic nuclei may contribute to gravitational wave\,(GW) events detected by grounded-based GW d…
Simulations on the collision between debris stream and outer dusty torus: a possible channel for forming fast-rise and long-delayed radio outburst in tidal disruption events
Xiangli Lei, Qingwen Wu, Hui Li +6
The geometrically thick dusty torus structure is believed to exist in the nuclear region of galaxies (especially in active galactic nuclei, AGNs). The debris stream from a tidal di…
Exploring the properties of photosphere and emission lines for tidal disruption events based on the global solution of slim disk and winds
Yuehua Zhang, Qingwen Wu, Jiancheng Wu +2
The theoretical debris supply rate from a tidal disruption of stars can exceed about one hundred times of the Eddington accretion rate for a supermassive black…
The weakness of soft X-ray intensity: possible physical reason for weak line quasars
Jiancheng Wu, Qingwen Wu, Chichuan Jin +8
Weak-line quasars (WLQs) are a notable group of active galactic nuclei (AGNs) that show unusually weak UV lines even though their optical-UV continuum shapes are similar to those o…
