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…
How far is quasar UV/optical variability from damped random walk at low frequency?
Hengxiao Guo, Junxian Wang, Zhengyi Cai +1
Studies have shown that UV/optical light curves of quasars can be described with the prevalent damped random walk (DRW, also known as Ornstein-Uhlenbeck process) model. A white noi…
