Abstract: Our research significantly provides two more direct detections on molecular outflows from starburst galaxies NGC 2146 and NGC 3628. Our Nobeyama Millimeter Array (NMA) CO(1-0) observations successfully detect sub-kpc to kpc scale molecular outflows in both galaxies. The kinetic energies of molecular outflows are at least 1054–55 erg, which corresponds to tens of thousands supernova explosions. Combining our NMA CO(1-0) data and the Chandra X-ray Observatory (CXO) archival data, we found that the molecular outflows keep moving outward and losing their molecular gas mass. This strongly suggests that the process of outflows plays an important role to impede star forming activities in starburst galaxies.
