    Efficiency of massive star formation in grand design spirals
    The present study estimates the efficiency ratio for massive star formation between the arms and the interarm disks of three grand design spirals. The estimate...

    Evidence for coherent star-forming processes in the discs of spirals
    This paper presents examples of star-forming phenomena in the discs of spirals which show symptoms of phase-coherence over kpc scales. Cases are found where...
