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…
Characterizing the origins of gamma-ray variability of the jetted active galactic nuclei observed with the Fermi-LAT
Yongyun Chen, Qiusheng Gu, Junhui Fan +5
We conducted an analysis of gamma-ray variability in a large sample of jetted active galactic nuclei (AGNs) by utilizing archival Fermi-LAT light curves and applying damped random…
A universal relationship between the variability timescale and black hole mass in black hole jetted and non-jetted accreting systems
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
A long-term variability study spanning a range of black hole mass systems, from microquasars hosting stellar-mass black holes to active galactic nuclei (AGNs) harboring supermassiv…
A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane
Zhen Cao, Felix Aharonian, Yunxiang Bai +312
Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes,…
A characteristic optical variability time scale in jetted active galactic nuclei: a large gamma-ray emission sample
Dingrong Xiong, Mouyuan Sun, Jun-Xian Wang +14
The variability mechanisms from jetted AGNs are still under debate. Here the damped random walk (DRW) model, implemented through Gaussian Processe (GPs), is used to fit the l…
The relation between black hole spin, star formation rate, and black hole mass for supermassive black holes
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
Both theoretical models and observational evidence indicate that jets and/or outflows driven by central active supermassive black holes exert a significant feedback effect on the o…
The relation between black hole spin and star formation in massive star-forming galaxies
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
It has always been believed that feedback from active galactic nuclei (AGN) has an important impact on star formation in massive galaxies. Black hole spin is an important physical…
The relation between black hole spin and molecular gas in massive galaxies
Chen Yongyun, Gu Qiusheng, Fan Junhui +4
Molecular gas is the key probe for the complex interaction between the accretion of black holes and star formation of the host galaxy of active galactic nuclei (AGN). The molecular…
Jets, accretion and spin in supermassive black holes
Yongyun Chen, Qiusheng Gu, Jianghe Yang +5
The theoretical model suggests that relativistic jets of AGN rely on the black hole spin and/or accretion. We study the relationship between jet, accretion, and spin using supermas…
Systematic Search and Study of Short-Timescale Flare Structures in BL Lac object Gamma-ray Emission
Jinjie Yu, Nan Ding, Junhui Fan +2
We present here the first systematic search of short timescale -ray flares from 29 high Galactic latitude BL Lac objects over 14 years of Fermi Large Area Telescope data. Using…
Very Long Baseline Array Observations of Parsec-scale Radio Emission in Dual Active Galactic Nuclei
Wancheng Xu, Lang Cui, Xiang Liu +11
It is believed that dual active galactic nuclei (dual AGN) will form during galaxies merge. Studying dual-AGN emission can provide valuable insights into galaxy merging and evoluti…
General Physical Properties of Gamma-Ray-emitting Radio Galaxies
Yongyun Chen, Qiusheng Gu, Junhui Fan +4
We study the radio galaxies with known redshift detected by the Fermi satellite after 10 years of data (4FGL-DR2). We use a one-zone leptonic model to fit the quasi-simultaneous mu…
Curvature of the spectral energy distribution, Compton dominance and synchrotron peak frequency in jetted AGNs
Chen Yongyun, Gu Qiusheng, Fan Junhui +4
We collect a large sample with a reliable redshift detected by the Fermi satellite after 10 years of data (4FGL-DR2), including blazars, -ray Narrow-line Seyfert 1 galaxies (…
