Electron Densities in AGN Outflows</b></p>
<p align="center"><b><br>
</b></p>
<p align="center">AGN outflows are critical for understanding
galaxy evolution, but current observational techniques to
measure their impact are plagued by high uncertainties. The
primary culprit of this uncertainty is the electron density of
the ionized outflow, which can vary by over three orders of
magnitude. Consequently, current models of galactic evolution
cannot be trusted, and new observational methods are desperately
needed. In this talk, I will describe a new technique for
estimating the AGN electron densities more precisely and then
show how that method can be used to study different types of
galactic outflows. Specifically, I will examine this new method
by combining new Keck/KCWI integral field spectroscopic
observations with CLOUDY photoionization modeling in order to
find an emission line tracer that precisely measures electron
densities. Finding a better way to constrain the electron
densities in ionized outflows will have a profound impact not
only on research in AGN but also on the entire field of galaxy
evolution.</p>
