Quasi-periodic variability observed in two blazars

An international team of astronomers reports the detection of quasi-periodic variability in optical and gamma-ray light curves of two blazars, namely 3C 66A and B2 1633+38. The discovery could be helpful in advancing our knowledge about such behavior in blazars. The finding is detailed in a paper published January 16 on arXiv.org.
