Scientific paper

A jet plasmoid model for 3C449 has been constructed by introducing a plasma-ejecting black hole orbiting around the center of its parent cD galaxy. We examined the characteristics of the jet trajectory by varying the values of (1) orbiting radius and velocity of the black hole, (2) plasma ejection velocity, (3) size, mass and space velocity of the parent galaxy, (4) size of the galactic core, and (5) the density of intergalactic medium. In our model calculation the effect of the gravity by the parent galaxy and the ram pressure by the intergalactic medium have been taken into account. It is found that our dynamical model accounts reasonably well for the observed structure of 3C449. Our proposed model suggest that the buoyancy force near the galactic center plays an important role in the formation of the curved structure of the radio jet.
