Month-scale QPO in OP 313 Gamma-ray Light Curve

This paper investigates the potential for detecting a month-scale quasi-periodic oscillation (QPO) in the gamma-ray light curve of the blazar OP 313. The authors analyze Fermi-LAT data and find tentative evidence for a QPO, although the significance is limited by the data length. The study explores potential physical origins, suggesting a curved-jet model as a possible explanation. The work is significant because it explores a novel phenomenon in a blazar and provides a framework for future observations and analysis.

• •The paper reports potential detection of a month-scale QPO in the gamma-ray light curve of OP 313.
• •Analysis uses Fermi-LAT data and Bayesian block method.
• •Detection significance is currently limited by data length.
• •A curved-jet model is proposed as a possible explanation for the QPO.
