The variability of 30 PG quasars has been observed in the red band during three years. A rest-frame structure function analysis shows an increase of variability with the time interval up to 0.2 mag r.m.s. after two years. A comparison with the IUE data available for PG quasars shows that the variability increases with the rest-frame frequency at each time interval. Evidence for this effect is supported by the analysis of the average variability of other published quasar samples. The effect can completely account for the increase of variability with redshift found in other studies.

  1. Weak-emission-line quasars: A new clue from their optical variability

    astro-ph.GA 2025-01 conditional novelty 6.0 of 10

    Weak-emission-line quasars show systematically weaker optical variability (factor ~1.76 in amplitude) on month/year timescales than matched normal quasars.
