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…
Simulating the timescale dependent color variation in quasars with a revised inhomogeneous disk model
Zhen-Yi Cai, Jun-Xian Wang, Wei-Min Gu +4
The UV/optical variability of active galactic nuclei and quasars is useful for understanding the physics of the accretion disk and is gradually attributed to the stochastic fluctua…
The Discovery of Timescale-Dependent Color Variability of Quasars
Yu-Han Sun, Jun-Xian Wang, Xiao-Yang Chen +1
Quasars are variable on timescales from days to years in UV/optical, and generally appear bluer while they brighten. The physics behind the variations in fluxes and colors remains…
