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

Universe
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.

VLBI Analysis of a Potential High-Energy Neutrino Emitter Blazar

Universe
Recent studies suggest that high-energy neutrinos can be produced in the jets of blazars, radio-loud active galactic nuclei (AGN) with jets pointing close to the line of sight.
