英文摘要
It is important to study gas motion in the central region of galaxies to understand the possible existence and environment around the central black hole. We selected absorption lines of ammonia for this purpose. In Arp 220 known as an active galaxy we analyzed obtained data. During data acquisition and analysis we considered to increase the reliability of the line width of the absorption lines. The (J,K)=(3,3) line was analyzed in detail, and as a result the full width was derived to be about 600km/s. This value is usual in galaxies, and we concluded that there is no significant violent motion in gas detectable with ammonia in the central region in Arp 220
