Multi-frequency Radio Measurements of SN 1987A over 22 Years
G. Zanardo, L. Staveley-Smith, Lewis Ball +6
We present extensive observations of the radio emission from the remnant of SN 1987A made with the Australia Telescope Compact Array (ATCA), since the first detection of the remnan…
First Detection of Ammonia in the Large Magellanic Cloud: The Kinetic Temperature of Dense Molecular Cores in N159W
Juergen Ott, Christian Henkel, Lister Staveley-Smith +1
The first detection of ammonia (NH3) is reported from the Magellanic Clouds. Using the Australia Telescope Compact Array, we present a targeted search for the (J,K) = (1,1) and (2,…
Diffuse RRL emission on the Galactic plane between l=36 to 44 degrees
Marta I. R. Alves, Rodney D. Davies, Clive Dickinson +4
Radio recombination lines (RRLs) can be used to determine the emission measure unambiguously along the Galactic plane. We use the deep (2100s per beam) HI Parkes Zone of Avoidance…
The velocity function of gas-rich galaxies
Martin Zwaan, Martin Meyer, Lister Staveley-Smith
We measure the distribution function of rotational velocities phi(V_c) of late-type galaxies from the HIPASS galaxy catalogue. Previous measurements of the late-type velocity funct…
The Australia Telescope 20 GHz Survey: The Source Catalogue
Tara Murphy, Elaine M. Sadler, Ronald D. Ekers +21
We present the full source catalogue from the Australia Telescope 20 GHz (AT20G) Survey. The AT20G is a blind radio survey carried out at 20 GHz with the Australia Telescope Compac…
High Resolution X-ray Imaging of Supernova Remnant 1987A
C. -Y. Ng, B. M. Gaensler, S. S. Murray +5
We report observations of the remnant of Supernova 1987A with the High Resolution Camera (HRC) onboard the Chandra X-ray Observatory. A direct image from the HRC resolves the annul…
High resolution 36 GHz imaging of the Supernova Remnant of SN1987A
T. M. Potter, L. Staveley-Smith, C. -Y. Ng +6
The aftermath of supernova (SN) 1987A continues to provide spectacular insights into the interaction between a SN blastwave and its circumstellar en- vironment. We here present 36…
The Second Survey of the Molecular Clouds in the Large Magellanic Cloud by NANTEN. II. Star Formation
A. Kawamura, Y. Mizuno, T. Minamidani +7
We studied star formation activities in the molecular clouds in the Large Magellanic Cloud. We have utilized the second catalog of 272 molecular clouds obtained by NANTEN to compar…
Properties and Origin of the High-Velocity Gas Toward the Large Magellanic Cloud
N. Lehner, L. Staveley-Smith, J. C. Howk
In the spectra of 139 early-type Large Magellanic Cloud (LMC) stars observed with FUSE and with deep radio Parkes HI 21-cm observations along those stars, we search for and analyze…
Cool Gas in the Magellanic Stream
D. Matthews, L. Staveley-Smith, P. Dyson +1
We present the first direct detection of cold atomic gas in the Magellanic Stream, through 21 cm line absorption toward a background radio source, J0119 - 6809, using the Australia…
GASS: The Parkes Galactic All-Sky Survey. I. Survey Description, Goals, and Initial Data Release
N. M. McClure-Griffiths, D. J. Pisano, M. R. Calabretta +11
The Parkes Galactic All-Sky Survey (GASS) is a survey of Galactic atomic hydrogen (HI) emission in the Southern sky covering declinations using the Parkes Radio T…
