| Abstract: | Since the first extragalactic H2O megamaser source toward the Active Galactic Nuclei NGC 4945 was discovered, 19 sources have been found. The observational study of extragalactic H2O megamaser sources and molecular emission lines associated with AGNs is a very efficient tool to investigate characteristics of certral sources in AGNs and circumnuclear toruses of gases and dusts. Current researches of searching, observation and theory on extragalactic H2O megamaser sources and associated molecular emission lines are mainly reviewed in this paper. |
