Description
It is a well established fact that AGNs show large amplitude flux and occasional quasi periodic oscillations (QPOs) in their X-ray light curves. For the last 1.5 decades, my group has extensively worked on searching for X-ray variations in two subclasses of active galactic nuclei (AGNs) namely narrow line Seyfert 1 (NLSy1) and blazars. We have used various X-ray missions e.g. MAXI, XMM-Newton, Chandra, Suzaku, NuStar, etc. In the present talk, I will summarize key results of our work, and possible theoretical explanations.
