The Awakening Beast in the Seyfert 1 Galaxy KUG 1141+371 I
Jiachen Jiang, Huaqing Cheng, Luigi C. Gallo +10
KUG 1141+371 is a Seyfert 1 galaxy that shows a simultaneous flux increase in the optical and UV bands in the past decade. For instance, the latest Swift observation in 2019 shows…
Magnetic-reconnection-heated corona in active galactic nuclei: refined disc-corona model and application to broad-band radiation
Huaqing Cheng, B. F. Liu, Jieying Liu +3
A long-standing question in active galactic nucleus (AGN) research is how the corona is heated up to produce X-ray radiation much stronger than that arising from the viscous heatin…
Multiwavelength Study of an X-ray Tidal Disruption Event Candidate in NGC 5092
Dongyue Li, R. D. Saxton, Weimin Yuan +7
We present multiwavelength studies of a transient X-ray source, XMMSL1 J131952.3+225958, associated with the galaxy NGC 5092 at detected in the XMM-Newton SLew survey (XM…
The Large Amplitude X-ray Variability in NGC 7589: Possible Evidence for Accretion Mode Transition
Zhu Liu, He-Yang Liu, Huaqing Cheng +2
We report the discovery of large amplitude X-ray variability in the low luminosity AGN (LLAGN) MGC 7589, and present possible observational evidence for accretion mode transition i…
Modeling accretion disk emission with generalized temperature profile and its effect on AGN spectral energy distribution
Huaqing Cheng, Weimin Yuan, He-Yang Liu +3
The broadband spectral energy distribution (SED) of Active Galactic Nuclei (AGN) is investigated for a well-selected sample composed of Seyfert 1 galaxies observed simultaneou…
