Abstract
An AO-assisted integral-field spectrograph is becoming the most efficient tool with which to explore ionized gas outflows. It maps faint spectral lines that diagnose cloud dust content, gas pressure, excitation mechanism, and chemical abundances. Coupled with recent improvements in photoionization models, the total mass hence flow energetics can be estimated. Establishing a consistent dynamical framework requires linking multi-frequency datasets to track the energy flow through its optimal-contrast emission in the various ISM phases. I show HST results on AGN, starburst nuclei, and Galactic Herbig-Haro Objects that need complementary 3D spectra at comparable spatial resolution to come soon from laser-guided AOÂ +Â integral-field spectrographs at the William-Herschel and SOAR telescopes.
