Abstract : Radio Loud Active Galactic Nuclei (RLAGNs) show the presence of extended jets that are well-collimated plasma flows. Sometimes, they show significant distortion in their structure, leading to an S-shaped morphology. These winged sources are one of the rare radio structures in the sky and are predicted to be the outcome of a precessional jet. The existence of the dual AGN at the center of these galaxies is proposed as one of the plausible mechanisms in order to explain the precession. The goal of this work is to study the formation of S-morphology due to the precessional jet through numerical means. In this regard, we have performed a full-scale 3D MHD simulation of jet propagating in an ambient galaxy and have shown that a precessional jet can lead to the formation of a distinct S-shape. The parametric restrictions under which this S-morphology forms will be presented along with the effect of the magnetic field in the dynamical evolution. Further, the implication of the parameter study on emission properties and age determination will be discussed, which will help to understand the spectral properties of S-shaped radio sources.
