SWS Central Program--- Galaxies (170 hr; 39%)

• Spectroscopy of bright galactic nuclei (Genzel et al.).
  • 116 hr.
  • Properties of circumnuclear ISM.
  • Properties of central energy source(s).
  • Brightest lines in 55 normal, SB, LINER, Seyfert, QSO's, FIR ultralums.
  • Wide range of atomic, ionic, and molecular lines.
• Spectroscopy of star forming regions in Local Group galaxies (van de Hulst).
  • 36 hr.
  • Physical conditions of gas.
    • Targets: Brightest H II regions in LMC, SMC & M33.
    • Cool gas at interface of H II region.
    • Ionized gas in H II region and surrounding molecular cloud.
    • Molecular gas and dust heated by ionizing stars.
    • Study role of metallicity.
• Photometry of radio galaxies and quasars (de Graauw).
  • Matched Samples of 3RC Radio Galaxies and QSO's.
    • Investigate barthel et al. unification model.
    • Since FIR samples thermal re-radiation, QSO's and RG's should have matched FIR properties.
    • Obs. at 25, 60, 90 & 160 um ~ 10X more sensitive than IRAS.
  • Subset of Complete Molonglo Southern 4Jy (MS4) Sample
    • Obs. at 60, 90 & 160 um ~ 5X more sensitive than IRAS.
