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…

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…

A Composite Broad-Line Region in SDSS J1609+4902: a Double-Peaked Disk component and a Gaussian Component

Jiancheng Wu, Qingwen Wu, Chen Hu +6

The profiles of broad emission lines in active galactic nuclei (AGNs) provide critical insights into the geometry and kinematics of the broad-line region (BLR), which in turn influ…

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…

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…

The Interaction Between Stars and Past AGN Disk: Possible Explanation for the Kinematic Distributions of S-stars in the Galactic Center

Xiao Fan, Qingwen Wu, Jiancheng Wu +3

The presence of young stars, aged around several million years and situated within the range of pc from our Galactic center raises a question about their origins and…

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…

Steep Balmer decrement in weak AGNs may be not caused by dust extinction: clues from low-luminosity AGNs and changing-look AGNs

Jiancheng Wu, Qingwen Wu, Hanrui Xue +2

The hydrogen Balmer decrement (e.g., ) is widely adopted as an indicator of the internal reddening of active galactic nuclei (AGNs). This is challenged by some low-lumin…
