TL;DR: In this paper, two diffuse expanding molecular superbubbles and one molecular outflow are successfully detected from a deep (1 sigma = 5.7 mJy beam^{-1} per 20.8 km s−1} velocity channel) interferometric observation of the central 60" region of the nearby edge-on starburst galaxy NGC 2146 observed with the NMA.
