The ten quasars with the highest radio core luminosity at 5 GHz in the Palomar Bright Quasar Survey were selected for this monitoring program; Seven out of the ten radio-luminous quasars exhibited signs of short-term variability, and all ten radio-luminous quasars showed signs of long-term variability. We assume our QSO cores have high radio luminosities because they have a jet of relativistic material aligned close to our line-of-sight; we would then expect to see more variability than in a sample of radio-quiet QSOs if the shock in the jet is the cause of variability. There is evidence that our radio-loud QSOs are more likely to have short-term variations compared to samples of radio-quiet QSOs. This finding supports the model of QSO variability being caused by shock waves in the relativistic plasma jet.","abstract_html":"The goal of this project is to test the shocked jet model for quasar variability at optical wavelengths.
