Assigned ID: 295 ----- Submission 1 (Fri Jan 21 18:57:32 GMT 2005) ----- We propose to study the three-dimensional nature of AGN outflows.To some degree one can interpret and model the outflows assuming axial symmmetry. However, HST observations show directly and indirectly that AGN outflows are very asymmetric. Axisymmetric radiation driven disk wind models, such as developed by us, have sufficient predictive power to make direct contact between theory and observations. Our model can successfully explain launching and acceleration of AGN winds as well as predicts synthetic line profiles which are consistent with highly blueshifted absorption lines. However, the model seriously underestimates the line emission and does not predict multicomponent absorption. Thus, the model does not fully capture the complex wind geometry. Because the model has many successes, the above difficulties suggest that the model is incomplete rather than wrong. Therefore, we plan to take the natural step of generalizing the model to three-dimensions and address the above issues within a relatively simple disk wind scenario. We will continue to use the multi-dimensional, time-dependent, magnetohydrodynamical code ZEUS to compute the wind structure. We will also compute synthetic line profiles and continuum spectra based on the theoretical model. We plan to broaden our focus and consider the problem of line emission as well as line absorption. The key element of our project is a comparison of our synthetic profiles with HST and other observations.
