The dominant emission is originated by non-thermal processes from high energy particles. Multi-wavelength observations covering a wide spectrum from Radio wavelengths to TeV Gamma ray emission provides valuable insights into the micro-physical processes that occur in jets that lead to the observed radiation. The length scales associated with these micro-physical processes are many orders of magnitude smaller than the physical jet scales that can range up to few tens of kilo-parsec. Connecting a bridge between these scales poses a serious challenge to theoretical modeling of the emission from AGN jets. In this talk, I will present our recent hybrid numerical framework developed for PLUTO code to quantitatively connect such disjoint scales by simulating multi-dimensional flow pattern treating small-scale plasma processes in a sub-grid manner. In particular, I will emphasize on the role of magnetized shocks, commonly observed in AGN jets, in accelerating particles and its influence in governing the non-thermal emission and polarisation due to synchrotron and Inverse Compton processes. |
