Optical Quasi-Periodic Oscillation of Blazar PKS 1440-389 in the TESS Light Curve

Optical Quasi-Periodic Oscillation of Blazar PKS 1440-389 in the TESS Light Curve

We report the results of time series analysis of blazar PKS 1440-389, observed by the Transiting Exoplanet Survey Satellite (TESS) in two sectors. We find that the source has a quasi-periodic oscillation (QPO) of about 3.1 days for sector 11 and around 3.7 days for sector 38 in the optical band. We...
