Circular polarization effects induced by photon-axion mixing in astrophysical environments
Meng Wang, Nan Ding, Qiusheng Gu +2
Axions and axion-like particles (ALPs) are compelling candidates for dark matter and new physics beyond the Standard Model. Photon-axion mixing in external magnetic fields modifies…
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…
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…
