|Abstract : ||Blazar lightcurves display a rapid, aperiodic variability and sometimes a quasi-periodic oscillation (QPO) behaviour, on diverse time scales ranging from few hundreds of seconds to few years. The variability can be due to many reasons including injection of particles into the jet from the disc region, magnetic reconnection and the turbulence in independently emitting active zones. Apart from having a rapid and erratic lightcurve, many of the blazars are also usually found in inactive states showing very less variability.
The current work has been done over a set of 15 Blazars that have been observed by Transiting Exoplanet Survey Satellite (TESS) in different sectors in which a total of 32 sectors were there where the cleaning of raw data were successfully executed, fulfilling the optimum values range of output parametrs. Many of the sources showed negligible variability indicating an inactive state currently, however many of them showed huge variability even upto 10%.|
