PI: Nicholas Scoville California Institute of Technology CoI: Shawn Ewald, Senior Scientist Caltech Y ------------------------------------------------------------------------------------ 5. Abstract We shall use high resolution broadband and H-alpha photometric images of dust lanes in M51, combined with radio maps of the same regions, to determine local physical conditions. ------------------------------------------------------------------------------------ Observations Description ------------------------ Imaging of a near-nulcear region of M51.
