[13.06] Numerical Simulations of Narrow Angle Tailed Radio Sources : The Jones and Owen Model

Michael L. Norman, Dinshaw Balsara and Chris O'Dea ( National Center for Supercomputing Applications, Univ. of Illinois)

In previous work, Balsara and Norman (1992), we had focussed on simulating narrow angle tailed radio sources as fluid beams that are bent by the ram pressure of a cross flowing ICM. This allowed a comparison with several observable attributes of NAT sources. In particular we were able to make estimates of bending rate, beam profile, radial evolution and formation and interspacing of knots. The previous work suffered from the fact that the ISM of the host galaxy was not represented. In this work we remove that restriction by representing the host galaxy's ISM self-consistently using the prescription given in Balsara, Livio and O'Dea (1994). We then run jets through it and compare with observations.
