Description
Relativistic magnetized jets are common features of Active Galactic Nuclei (AGNs), that feature multi-timescale variability and a non-thermal spectrum ranging from radio to gamma-raysThese highly magnetized jets are prone to undergo several Magneto-hydrodynamic (MHD) instabilities during their propagation in space and could trigger jet radiation and particle acceleration. In this work, we study the implications of relativistic kink mode instability on the observed long-term variability in the context of the twisting in-homogeneous jet model. We found that with the evolution of the instability, the plasma column gets turbulent in nature and generates localized shocks. These shocks give rise to flaring signatures in the high-energy band which is also evident from the instantaneous flattening of the synchrotron component of the SEDs. Additionally, we will discuss the impact of such instability-driven shocks on the synchrotron polarization signatures.
