AGN Shocks in 3D

Summary

I review observable manifestations of various AGN shocks, discuss some key past 3D results, and outline some recent improvements in the computational framework within which spectra are interpreted. New models of dusty clouds broaden the scope of photoionization by providing a self-consistent basis for the successful matter-bounded/ionization-bounded model sequences, and can undermine the case for shocks in some AGN. However, we are only beginning to explore computationally the time evolution of shocks in 3D. The cyclical nature of high-velocity shock compression may provide a natural time scale for some AGN phenomena. It would be premature to dismiss a r ôle for shocks in datasets that encompass only a few strong emission-lines. We need comprehensive IFU spectra.
