Abstract : A small fraction of the ejected jets from Active Galactic Nuclei (AGN) are found to be deviating from their intended path, creating peculiar winged radio galaxies. Some of these sources raise X-shaped morphology by bending the jet in opposite direction producing inversion symmetric structures. Because of this peculiarity, the formation mechanism of such sources is still debated, with the debate relating the origin to the asymmetric ambient medium or any complex activities occurring in the AGN. As more low-frequency radio observations and high-resolution X-ray observations become available, unravelling the macro-physics responsible for their formation is becoming increasingly difficult because of the complexity observed associated with them. In this regard, we have performed numerical simulations using hybrid Eulerian-Lagrangian framework and the Adaptive Mesh refinement techniques to shed some light on the origin and evolution of these galaxies by better capturing the underlying physical processes. Use of these updated approaches has helped us understand the unusual spectral properties observed in these sources, which will be showcased along with their correlation to the diffusive shock acceleration mechanism. We will also discuss how the formed morphology varies based on viewing angle and different formation scenarios. Furthermore, the X-ray map obtained of the ambient cluster medium of such galaxies from our simulations will also be showcased, along with a discussion on what information they share while determining the macro-physics of these galaxies.
