Title: Multi-wavelength variability and QPOs (Quasi Periodic Oscillations) in Blazars 

Speaker: Alok Gupta (ARIES, India) 

Time: Thursday , 10:00am,Jan 22 

Location: the middle conference room 

 

Abstract: With enhanced multi-wavelength facilities and revolution due to communication facilities, now a days, doing simultaneous multi-wavelength observations of astronomical objects have become possible and very helpful to understand the physics of emission in different EM bands.Blazar is a sub-class of radio-loud AGN which emit radiation in the complete EM spectrum. The emission is highly variable, and predominantly non-thermal. So, blazars are among one of the best targets to study in simultaneous in complete EM band. In the present colloquium, I would report our recent results based on multi-wavelength blazars flux and polarization variability, spectral energy distribution, and detection of quasi-periodic oscillations in time series data on diverse timescales.
