Abstract
We discuss the possible observational signatures resulting from the in teraction of a nuclear wind with an elliptical host galaxy. The ioniza tion parameter in emission-line gas, deduced from spatially resolved s pectral observations, will be a strong indicator of the nuclear wind a s well as the possible pickup of stellar mass loss by the wind. If the wind is sufficiently luminous, galactic X-ray profiles will exhibit a n extended flattening. Detailed study of individual objects will be ne cessary for conclusive evidence of nuclear winds. We find that nuclear winds are unlikely to cause the disruption of the radio jets in wide- angle tail radio galaxies. Previously proposed mechanisms whereby nucl ear winds cause the formation of narrow absorption fine systems or ste llar shells are not likely to occur if the interstellar medium of the host elliptical galaxy is hot.
