    Observations of Massive Supersonic Outflows in Highly Luminous H II Regions
    Using H alpha emission line profiles we detect outflowing ionized gas at velocities of order 50 km/s from representative luminous H II regions in two sample...

    Observations of outflow and its consequences in circum-nuclear zones of spirals
    The radial hydrogen (H2 + HI) distribution in spirals takes two forms: with a density peak at the nucleus or with a circular 'hole' around it. Spectral and...

    Observations of the J = 2 - 1 transitions of /C-12/ /O-16/ and /C-12/ /O-18/ towards galactic H II regions
    Observations are reported of the J = 2 → 1 transitions of CO and 12C18O at 230 and 219 GHz respectively from a number of galactic sources. A map of the central...
