Physical and chemical conditions in methanol maser selected hot-cores and UCHII regions
C. R. Purcell, S. N. Longmore, M. G. Burton +4
We present the results of a targeted 3-mm spectral line survey towards the eighty-three 6.67 GHz methanol maser selected star forming clumps observed by Purcell et al. 2006. In add…
The 6-GHz Multibeam Maser Survey I. Techniques
J. A. Green, J. L. Caswell, G. A. Fuller +22
A new 7-beam 6-7 GHz receiver has been built to survey the Galaxy and the Magellanic Clouds for newly forming high-mass stars that are pinpointed by strong methanol maser emission…
In search of RR Lyrae type stars in eclipsing binary systems. OGLE052218.07-692827.4: an optical blend
A. Prsa, E. F. Guinan, E. J. Devinney +1
During the OGLE-2 operation, Soszynski et al. (2003) found 3 LMC candidates for an RR Lyr-type component in an eclipsing binary system. Two of those have orbital periods that are t…
New XMM-Newton observations of SNRs in the SMC
M. D. Filipovic, F. Haberl, P. F. Winkler +6
A complete overview of the supernova remnant (SNR) population is required to investigate their evolution and interaction with the surrounding interstellar medium in the Small Magel…
Optical Spectra of Radio Planetary Nebulae in the Small Magellanic Cloud
J. L. Payne, M. D. Filipović, E. J. Crawford +3
We present preliminary results from spectral observations of four candidate radio sources co-identified with known planetary nebulae (PNe) in the Small Magellanic Cloud (SMC). Thes…
Radio Continuum Study of Supernova Remnants in the Large Magellanic Cloud - SNR J0519-6926
E. J. Crawford, M. D. Filipović, J. L. Payne
We present the results of new high resolution ATCA observations of SNR J0519-6926. We found that this SNR exhibits a typical "horseshoe" appearance with alpha = -0.55 +- 0.08 and D…
A Pilot Survey for the HO Southern Galactic Plane Survey (HOPS)
Andrew J. Walsh, Nadia Lo, Michael G. Burton +5
We describe observations with the Mopra radiotelescope designed to assess the feasibility of the HO maser southern Galactic plane survey (HOPS). We mapped two one-square-degree…
Further Constraints on the Presence of a Debris Disk in the Multiplanet System Gliese 876
Paul D. Shankland, David L. Blank, David A. Boboltz +2
Using both the Very Large Array (VLA) at 7mm wavelength, and the Australia Telescope Compact Array (ATCA) at 3mm, we have searched for microwave emission from from cool dust in the…
Spectral imaging of the Sagittarius B2 region in multiple 3-mm molecular lines with the Mopra telescope
P. A. Jones, M. G. Burton, M. R. Cunningham +6
Using the Mopra telescope, we have undertaken a 3-mm spectral-line imaging survey of a 5 x 5 arcmin^2 area around Sgr B2. We covered almost the complete spectral the range from 81.…
ATCA 3mm observations of NGC6334I and I(N): dense cores, outflows and an UCHII region
H. Beuther, A. J. Walsh, S. Thorwirth +4
Aims: Investigation of the dense gas, the outflows and the continuum emission from the massive twin cores NGC6334I and I(N) at high spatial resolution. Methods: We imaged the regio…
Multibeam Maser Survey of methanol and excited OH in the Magellanic Clouds: new detections and maser abundance estimates
J. A. Green, J. L. Caswell, G. A. Fuller +21
We present the results of the first complete survey of the Large and Small Magellanic Clouds for 6668-MHz methanol and 6035-MHz excited-state hydroxyl masers. In addition to the su…
Kinematics of a hot massive accretion disk candidate
H. Beuther, A. Walsh
Characterizing rotation, infall and accretion disks around high-mass protostars is an important topic in massive star formation research. With the Australia Telescope Compact Array…
New ammonia masers towards NGC6334I
A. J. Walsh, S. N. Longmore, S. Thorwirth +2
We report the detection of new ammonia masers in the non-metastable (8,6) and (11,9) transitions towards the massive star forming region NGC6334I. Observations were made with the A…
Multi-frequency Study of the LMC Supernova Remnant (SNR) B0513-692 and New SNR Candidate J051327-6911
I. S. Bojicic, M. D. Filipovic, Q. A. Parker +5
We present a new multi-wavelength study of supernova remnant (SNR) B0513-692 in the Large Magellanic Cloud (LMC). The remnant also has a strong, superposed, essentially unresolved,…
A Statistical Study of Galactic SNRs using the PMN Survey
M. Stupar, M. D. Filipovic, Q. A. Parker +3
The Parkes-MIT-NRAO (PMN) radio survey has been used to generate a quasi all-sky study of Galactic Supernova Remnants (SNRs) at a common frequency of 4.85 GHz. We present flux dens…
Hot ammonia in NGC6334I & I(N)
H. Beuther, A. J. Walsh, S. Thorwirth +4
Aims: The massive twin cores NGC6334I and I(N) are in different evolutionary stages and hence ideal targets to study evolutionary variations within the same larger-scale environmen…
