Feedback from outflows in AGNs. III. Mrk78

However, determining the energetics of these outflows is difficult with spatially unresolved observations that are subject to strong global selection effects. We present part of an ongoing study using Hubble Space Telescope and Apache Point Observatory spectroscopy and imaging to derive spatially resolved mass outflow rates and energetics for narrow-line region outflows in nearby AGN that are based on multi-component photoionization models to account for spatial variations in gas ionization, density, abundances, and dust content.

This expanded analysis adds Mrk 3, Mrk 78, and NGC 1068, doubling our earlier sample. We find that the outflows contain total ionized gas masses of M~10^5.5^-10^7.5^M_{sun}_ and reach peak velocities of v~800-2000km/s. The outflows reach maximum mass outflow rates of dM/dt_out_3-12M_{sun}_/yr and encompass total kinetic energies of E~10^54^-10^56^erg.
