报告提纲

• Several year-scale QPOs seem to be present in the multi-frequency blazar light curves.

• However, finding QPOs in blazars is a challenging task due to several artifacts present is the observation.

• Many models can explain the periodic oscillations.

• Multi-frequency approach should break the degeneracy in the models.

• Such QPOs could make an excellent probe to the innermost regions of AGN including the extreme physical conditions near the supermassive black hole.

个人简介

Gopal Bhatta, Astronomical Observatory of the Jagiellonian University. Dr. Bhatta detected a transient QPO in the gamma-ray emission of the famous blazar Mrk 501.
