Analysis of the optical variability
Correlated X ray/ultraviolet/optical variability in NGC 6814
... Using cross-correlation analysis, we compute the time lag between the X-ray and lower energy bands. These lags are thought to be associated with the light travel time between the central X-ray emitting region and ...
