    • Supernova feedback and the energy deposition in molecular clouds 

      Lucas, William E; Bonnell, Ian A; Dale, James (2020-04-01)
      Feedback from supernovae is often invoked as an important process in limiting star formation, removing gas from galaxies and, hence, as a determining process in galaxy formation. Here, we report on numerical simulations, ...
