| Abstract: | OH megamasers in circumnuclear torus are observed by using MERLIN. An
evidence of warped circumnuclear torus around the center of IRAS10173+0828 is obtained.
It is also obtained that angular sizes of contours to extend to both directions of East and
West in 10 velocity channels are correlated with the peak flux densities per beam positively. |
