Shot Noise in 3c 273

Shot Noise in 3c 273

The underlying impulse sequence responsible for the optical variability displayed by 3C 273 is presented. The sequence is random and consistent with a shot-noise process in which the mean rate of events is 8 yr/sup -1/. The implication of the result for proposed physical models is briefly discussed....

Zusammenfassung:The underlying impulse sequence responsible for the optical variability displayed by 3C 273 is presented. The sequence is random and consistent with a shot-noise process in which the mean rate of events is 8 yr/sup -1/. The implication of the result for proposed physical models is briefly discussed.
