Chinese astronomers have conducted a gamma-ray and optical variability analysis of the blazar 3FGL J0449.4-4350. The new research, presented in a paper published March 25 on arXiv.org, reports the detection of possible quasi-periodic oscillation (QPO) from the source and provides more insights into the origin of such behavior.
