Bright Blazar Reveals 433-Day Optical Quasi-Periodic Oscillation Across Nine Years
An international team analyzing 19 years of Whole Earth Blazar Telescope data has identified a 433‑day optical quasi‑periodic oscillation (QPO) in the bright flat‑spectrum radio quasar 3C 454.3.

Researchers considered both accretion‑disk and jet‑based models, with jet mechanisms currently favored but not definitively proven. The study, led by Karan Dogra of ARIES, underscores the value of long‑term multi‑observatory monitoring.
