Jet Power, Bulk Lorentz Factor, Black Hole Spin, and Magnetic Field of Accretion Disk in Jetted Active Galactic Nuclei: A Large Gamma-Ray Emission Sample
Dingrong Xiong, Junhui Fan, Feng Yuan +14
We present a catalog of physical parameters for powerful jet-accretion disk-black hole systems in one of the largest samples of gamma-ray emitting jetted active galactic nuclei (AG…
X-ray Fourier lag-frequency spectra modulated by stochastic turbulent acceleration in the jets of high-frequency-peaked BL Lac
Guang-Cheng Xiao, Wen Hu, Da-Guo Jiang +4
X-ray interband time lags are key diagnostics of jet physics and are frequently detected in high-frequency peaked BL Lac (HBL) objects at different epochs with various X-ray telesc…
X-ray Quasi-Periodic Oscillations in Active Galactic Nuclei and Their Implications for the Changing Look Phenomenon
Mouyuan Sun, Shuying Zhou, Jihong Liu +12
X-ray timing of active galactic nuclei (AGN) provides a unique probe of gas accretion onto supermassive black holes (SMBHs). Quasi-periodic oscillations (QPOs), which trace gas dyn…
Sizes of active galactic nuclei inhomogeneous disks -- large in microlensing, small in reverberation mapping
Guowei Ren, Mouyuan Sun, Jun-Xian Wang +1
Magnetohydrodynamics (MHD) turbulence can drive significant temperature fluctuations in the accretion disk of an active galactic nucleus (AGN). As a result, the disk can be highly…
Stellar black holes can "stretch'' supermassive black hole accretion disks
Shuying Zhou, Mouyuan Sun, Tong Liu +3
Stellar black holes (sBHs) are widely believed to exist in the accretion disks of active galactic nuclei (AGNs). Previous studies often focus on the transient emission produced by…
How long will the quasar UV/optical flickering be damped?
Shuying Zhou, Mouyuan Sun, Zhen-Yi Cai +3
The UV/optical light curves of Active Galactic Nuclei (AGNs) are commonly described by the Damped Random Walk (DRW) model. However, the physical interpretation of the damping times…
Faint AGNs Favor Unexpectedly Long Inter-band Time Lags
Ting Li, Mouyuan Sun, Xiaoyu Xu +12
Inconsistent conclusions are obtained from recent active galactic nuclei (AGNs) accretion disk inter-band time-lag measurements. While some works show that the measured time lags a…
