Scientific paper

The authors present new data on the stellar kinematics of twelve elliptical galaxies associated with powerful double radio sources. They combine these data with similar published data on nine other such galaxies. This sample of radio galaxies is then compared with a large sample of normal elliptical galaxies. It is found that the stellar kinematics of radio galaxies do not differ strongly in a systematic way from those of normal elliptical galaxies of comparable optical luminosity. In particular, the authors do not confirm earlier reports that radio galaxies are generically rapidly rotating, dynamically peculiar systems, nor do they find evidence for a general alignment between the stellar rotation axis and the radio ejection axis. The data do, however indicate that good alignment exists between the gas rotation and radio ejection axes in large (⪆100 kpc) sources. The gas dynamics are apparently more important than the stellar dynamics in influencing the formation and/or propagation of radio jets.
