By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the most persistent QPOs detected in the optical band. The finding was reported in a paper published April 30 on the arXiv pre-print server.
