New Clues to Jet Launching: The inner disks in radio loud quasars may be more stable
Zhen-Yi Cai, Yu-Han Sun, Jun-Xian Wang +3
Jet launching in radio loud (RL) quasars is one of the fundamental problems in astrophysics. Exploring the differences in the inner accretion disk properties between RL and radio q…
An intrinsic link between long-term UV/optical variations and X-ray loudness in quasars
Wen-yong Kang, Jun-Xian Wang, Zhen-Yi Cai +5
Observations have shown that UV/optical variation amplitude of quasars depend on several physi- cal parameters including luminosity, Eddington ratio, and likely also black hole mas…
On Measuring the Variation of High Energy Cut-off in Active Galactic Nuclei
Ji-Xian Zhang, Jun-Xian Wang, Fei-Fan Zhu
The variation in the high energy cut-off E_c in active galactic nuclei uniquely probes the corona physics. In this work we show that the ratio of two NuSTAR spectra (in analogy to…
EUCLIA - Exploring the UV/optical continuum lag in active galactic nuclei. I. a model without light echoing
Zhen-Yi Cai, Jun-Xian Wang, Fei-Fan Zhu +4
The tight inter-band correlation and the lag-wavelength relation among UV/optical continua of active galactic nuclei have been firmly established. They are usually understood withi…
On the UV/optical variation in NGC 5548: new evidence against the reprocessing diagram
Fei-Fan Zhu, Jun-Xian Wang, Zhen-Yi Cai +3
The reprocessing scenario is widely adopted in literature to explain the observed tight inter-band correlation and short lags in the UV/optical variations of active galactic nuclei…
The Timescale-Dependent Color Variability of Quasars Viewed with GALEX
Fei-Fan Zhu, Jun-Xian Wang, Zhen-Yi Cai +1
In recent work done by Sun et. al., the color variation of quasars, namely the bluer-when-brighter trend, was found to be timescale-dependent using SDSS band light curves in…
