Variabilities driven by satellite black hole migration in AGN disks
Jing-Tong Xing, Tong Liu, Bao-Quan Huang +1
The physical origin of active galactic nucleus (AGN) variability remains unclear. Here we propose that the magnetic reconnection induced by the migration of satellite black holes (…
The universal "heartbeat" oscillations in black hole systems accross the mass-scale
Qingwen Wu, Bozena Czerny, Mikolaj Grzedzielski +7
The hyperluminous X-ray source (HLX-1, the peak X-ray luminosity ) near the spiral galaxy ESO 243-49 is possibly the best candidate for intermediate ma…
On the origin of the HLX-1 outbursts
Mouyuan Sun, Wei-Min Gu, Zhen Yan +2
HLX-1, currently the best intermediate-mass black hole candidate, has undergone seven violent outbursts, each with a peak X-ray luminosity of $L_{\mathrm{peak},\mathrm{X}}\sim 10^{…
Thick Accretion Disk Model for Ultraluminous Supersoft Sources
Wei-Min Gu, Mou-Yuan Sun, You-Jun Lu +2
We propose a geometrically thick, super-Eddington accretion disk model, where an optically thick wind is not necessary, to understand ultraluminous supersoft sources (ULSs). For hi…
Fermi Bubbles Inflated by Winds Launched from the Hot Accretion Flow in Sgr A*
Guobin Mou, Feng Yuan, Defu Bu +2
A pair of giant gamma-ray bubbles have been revealed by the {\it Fermi} LAT. In this paper we investigate their formation mechanism. Observations have indicated that the activity o…
Time evolution of flares in GRB 130925A: jet precession in black hole accretion system
Shu-Jin Hou, Tong Liu, Wei-Min Gu +4
GRB 130925A, composed of three gamma-ray emission episodes and a series of orderly flares, has been detected by , Fermi, Konus-, and . If the third weakest g…
Do Intermediate-Mass Black Holes Exist in Globular Clusters?
Mou-Yuan Sun, Ya-Ling Jin, Wei-Min Gu +3
The existence of intermediate-mass black holes (IMBHs) in globular clusters (GCs) remains a crucial problem. Searching IMBHs in GCs reveals a discrepancy between radio observations…
Revisiting the Light Curves of Gamma-ray Bursts in the Relativistic Turbulence Model
Da-Bin Lin, Wei-Min Gu, Shu-Jin Hou +3
Rapid temporal variability has been widely observed in the light curves of gamma-ray bursts (GRBs). One possible mechanism for such variability is related to the relativistic eddie…
Understanding Simulations of Thin Accretion Disks by Energy Equation
Da-Bin Lin, Wei-Min Gu, Tong Liu +2
We study the fluctuations of standard thin accretion disks by linear analysis of the time-dependent energy equation together with the vertical hydrostatic equilibrium and the equat…
Gravitational Waves of Jet Precession in Gamma-ray Bursts
Mou-Yuan Sun, Tong Liu, Wei-Min Gu +1
The physical nature of gamma-ray bursts (GRBs) are believed to involve an ultra-relativistic jet. The observed complex structure of light curves motivate the idea of jet precession…
