A Shock-based Interpretation of Radio and X-ray Emission in Active Galactic Nuclei
Fan Wu, Benzhong Dai
We propose a shock-based framework to interpret the radio and X-ray emission in active galactic nuclei (AGNs), whose origin remains an open problem. In this framework, the radio em…
A Mass-Independent Damping Timescale in Black Hole Accretion Systems
Haoyang Zhang, Shenbang Yang, Li Zhang +1
The scaling laws reveal the underlying structural similarities shared by astrophysical systems across vastly different scales. In black hole accretion systems, the scaling relation…
Revisiting the observation-theory confrontation in high-frequency QPOs:a new QPO in NGC 5506, intermediate mass black holes, and the crucial role of accretion state
Haoyang Zhang, Lingwei Meng, Li Zhang +1
The scale invariance of accretion processes (SIAP) is crucial for understanding the physical processes of black hole accretion systems at different scales. When applying this rule…
Study of the gamma-Ray Radiation Properties of High-redshift Blazars at z>2.5
Fan Wu, Benzhong Dai
We study a sample of 30 high-redshift blazars () by means of spectra and the radiation mechanism with Fermi Large Area Telescope -ray observations spanning 15 years. Thr…
