Starburst galaxies display intense star forming activity and eject molecular gas into the intergalactic medium through galactic outflows. This process plays a key role on galaxy evolution. NGC3628 is a nearby starburst galaxy with several kpc hot ionized outflows. Therefore, we expected to see molecular gas exists in similar area of ionized outflows. The past CO observations do not detect galactic-scale molecular outflow due to its insufficient field of view and poor sensitivity. Our recent ARO CO observations detected molecular gas a few kpc above galactic disk. The limited angular resolution of those data prevents us to do a thorough study the morphology and the interaction between molecular gas and ionized gas. Right now we are using IRAM 30m CO observations with a significantly higher angular resolution to resolve the molecular gas distribution in the same area. We will present the newest results from this study.
