The Distinctive Evolution and Spectral Energy Distribution of Binary Massive Black Hole Accretion
Yue Xu, Fu-Guo Xie, Ya-Ping Li +2
Binary (super-)massive black holes (BHs) are expected to reside in the center of some galaxies. In this work, we re-visit accretion onto binary massive BHs, incorporating recent ad…
A "coronal-mass-ejection'' model for flares in Sagittarius A*
Xi Lin, Ya-Ping Li, Feng Yuan
High-resolution near infrared observations with GRAVITY instrument have revealed rapid orbital motions of a hot spot around Sgr A*, the supermassive black hole in our Galactic cent…
Spin Evolution of Stellar-mass Black Holes Embedded in AGN disks: Orbital Eccentricity Produces Retrograde Circumstellar Flows
Ya-Ping Li, Yi-Xian Chen, Douglas N. C. Lin +1
Spin evolution of stellar-mass Black Holes (sBHs) embedded in AGN accretion disks is an important process relevant to production of gravitaional waves from binary Black Hole (BBH)…
Hot Circumsingle Disks Drive Binary Black Hole Mergers in Active Galactic Nucleus Disks
Ya-Ping Li, Adam M. Dempsey, Hui Li +2
Binary black hole (BBH) mergers, particularly those with component masses in the pair-instability gap, may be produced by hierarchical mergers in the disks surrounding Active Galac…
Orbital evolution of binary black holes in active galactic nucleus disks: a disk channel for binary black hole mergers?
Ya-Ping Li, Adam M. Dempsey, Shengtai Li +2
We perform a series of high-resolution 2D hydrodynamical simulations of equal-mass binary black holes (BBHs) embedded in active galactic nucleus (AGN) accretion disks to study whet…
Self-organized Criticality in Multi-pulse Gamma-Ray Bursts
Fen Lyu, Ya-Ping Li, Shu-Jin Hou +3
The variability in multi-pulse gamma-ray bursts (GRBs) may help to reveal the mechanism of underlying processes from the central engine. To investigate whether the self-organized c…
