  • We have mapped the 2.6 mm CO J \ 1 ] 0 emission in three optically selected ii Toomre sequence ˇˇ mergers (NGC 520, NGC 3921, NGC 4676). The molecular gas distribution is well resolved by the observations. For NGC 520 and NGC 4676A, the nuclear gas concentrations form a disklike or a ringlike structure, and the gas kinematics are regular and consistent with simple rotation. Discrete molecular gas complexes are found along the stellar bar in NGC 4676B, and the gas kinematics is consistent with… CONTINUE READING
