  • Star formation in the Carina Nebula

    Using the Mopra telescope, we have targeted 61 regions in the Carina Nebula, covering an area of 1.5deg^2^, of bright and compact 870{mu}m dust continuum emission for molecular...
  • MMB Survey ex-OH catalogue

    We present the results of the first complete unbiased survey of the Galactic plane for 6035-MHz excited-state hydroxyl (ex-OH) masers undertaken as part of the methanol...
  • Optical redshifts of OH- and HI-emitting galaxies

    OH megamasers (OHMs) are rare, luminous molecular masers that are typically observed in (ultra) luminous infrared galaxies and serve as markers of major galaxy mergers. In blind...
  • 6.7-GHz methanol masers-dust associations

    We report the results of 870{mu}m continuum observations, using the Large APEX Bolometer Camera, towards 77 class-II, 6.7-GHz methanol masers identified by the Methanol...
  • Methanol maser associated outflows

    We have selected the positions of 54 6.7GHz methanol masers from the Methanol Multibeam Survey catalogue, covering a range of longitudes between 20{deg} and 34{deg} of the...
  • Southern methanol masers at 36 and 44GHz

    The Australia Telescope Compact Array (ATCA) has been used for high angular resolution imaging of 71 southern class I methanol maser sources quasi-simultaneously at 36 and...
  • 1.2-mm dust clumps with luminous water masers

    We have conducted a sensitive water maser search with the Australia Telescope Compact Array towards 267 1.2-mm dust clumps presented in the literature. We combine our new...
  • H_2_O Southern Galactic Plane Survey (HOPS)

    We present first results of the H_2_O Southern Galactic Plane Survey (HOPS), using the Mopra Radio Telescope with a broad-band backend and a beam size of about 2arcmin. We have...
  • High-mass SFR masers with VLBI & external MW-like gal.

    In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided...
  • 44GHz VLA obs. of methanol masers in DR21(OH)

    High-mass stars play an important role in the interstellar medium, but much remains to be known about their formation. Class I methanol masers may be unique tracers of an early...
  • Water masers in M31. I. Recombination lines

    We report the results of a Green Bank Telescope survey for water masers, ammonia (1,1) and (2,2), and the H66{alpha} recombination line toward 506 luminous compact 24{mu}m...
  • Water masers in M31. II. Multiwavelength data

    We present a comparative multiwavelength analysis of water-maser-emitting regions and non-maser-emitting luminous 24{mu}m star-forming regions in the Andromeda Galaxy (M31) to...
  • BGPS. XIV. Molecular cloud clumps GBT obs.

    We sort 4683 molecular clouds between 10{deg}<l<65{deg} from the Bolocam Galactic Plane Survey based on observational diagnostics of star formation activity: compact...
  • 95GHz methanol masers in molecular outflows

    We have observed a sample of 288 molecular outflow sources including 123 high-mass and 165 low-mass sources in order to search for class I methanol masers at the 95GHz...
  • Arecibo methanol maser Galactic Plane Survey

    We present the results of an unbiased survey for 6.7GHz methanol masers in the Galactic plane carried out using the 305m Arecibo radio telescope. A total of 18.2deg^2^ was...
  • Water maser emission in five AGNs

    We report the discovery of water maser emission in five active galactic nuclei (AGNs) with the 100m Green Bank Telescope (GBT). The positions of the newly discovered masers,...
  • Water masers associated with IR dark cloud cores

    We present a survey of the 6_16_-5_23_ H_2_O maser transition toward a sample of 140 compact cores in infrared dark clouds using the Very Large Array. Strong (>1Jy) H_2_O...
