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>
