- Water maser emission at 22 GHz, resolvable in position and velocity, provides a unique probe of the geometry and dynamics of the central parsec of highly obscured AGN. While only ~5% of narrow line AGN host water masers, this rarity is a clue to the physical processes in these AGN. We will present studies which show a link between maser emission and the obscuration, [OIII] luminosity (i.e. bolometric luminosity), and velocity dispersion (i.e. mass) of AGN. In addition, the narrow range in the temperature and density requirements for maser emission provide localized measurements of the temperature and density profiles within the parsec scale disks, enabling us to test theories on accretion and obscuration.
