Özet:
Water maser emission at 22 GHz provides a unique resolvable tracer of
warm, dense molecular gas in the inner parsec of active galactic nuclei
(AGNs). These maser systems have been used to probe a broad array of the
properties of the hosts, including the mass of the central supermassive black
hole (SMBH), the structure of the accretion disk, nuclear outflows, and the
geometric distance to the host galaxy. Unfortunately, extragalactic nuclear
maser emission is extremely rare and is found only in a few percent of
AGNs, making their discovery an arduous task. Recent studies have found
that maser emission is correlated with SMBH mass and activity, allowing
both a better understanding of the physical link between masers and their
hosts and a way to improve detection efficiency. This talk will discuss how
water masers can shed light on their AGN environments and vice versa.
