Environs of Bilateral Supernova Remnants with Neutron Stars

Author(s) : Dubner, G. , Giacani, E. , Gaensler, B. M. , Goss, W. M. , Green, A. J.
Description : We report on Australia Telescope Compact Array (ATCA) HI observations carried out in the direction of bilateral supernova remnants (SNRs) with associated neutron stars: G296.5+10.0 and G320.4--1.2, in a search for the origin of such morphology. From these studies we conclude that in the case of G2...

The Galactic Distribution of Large HI Shells

Author(s) : McClure-Griffiths, N. M. , Dickey, John M. , Gaensler, B. M. , Green, A. J.
Description : We report the discovery of nineteen new HI shells in the Southern Galactic Plane Survey (SGPS). These shells, which range in radius from 40 pc to 1 kpc, were found in the low resolution Parkes portion of the SGPS dataset, covering Galactic longitudes l=253 deg to l=358 deg. Here we give the proper...

Molecular Diagnostics of Supernova Remnant Shocks

Author(s) : Lazendic, J. S. , Wardle, M. , Green, A. J. , Whiteoak, J. B. , Burton, M. G.
Description : We have undertaken a study of radio and infrared molecular-line emission towards several SNRs in order to investigate molecular signatures of SNR shocks, and to test models for OH maser production in SNRs. Here we present results on G349.7+0.2. , Comment: 4 pages, 3 figures, appears in "Neutron Star...

Fitting Together the HI Absorption and Emission in the SGPS

Author(s) : Dickey, John M. , McClure-Griffiths, N. M. , Gaensler, B. M. , Green, A. J.
Description : In this paper we study 21-cm absorption spectra and the corresponding emission spectra toward bright continuum sources in the test region (326deg< l < 333 deg) of the Southern Galactic Plane Survey. This survey combines the high resolution of the Australia Telescope Compact Array with the full bri...

A Distant Extended Spiral Arm in the Fourth Quadrant of the Milky Way

Author(s) : McClure-Griffiths, N. M. , Dickey, J. M. , Gaensler, B. M. , Green, A. J.
Description : Using data from the Southern Galactic Plane Survey we present a possible distant spiral arm in the fourth quadrant of the Milky Way. The very distinct and cohesive feature can be traced for over 70 deg as the most extreme positive velocity feature in the longitude-velocity diagram. The feature is ...

OH (1720 MHz) Maser Search Toward the Large Magellanic Cloud

Author(s) : Brogan, C. L. , Goss, W. M. , Lazendic, J. , Green, A. J.
Description : We have carried out a sensitive search for OH (1720 MHz) masers in the Large Magellanic Cloud (LMC) toward five regions using the Australia Telescope Compact Array (ATCA). Our source list includes the 30 Doradus region, and four supernova remnants (SNRs): N44, N49, N120, and N132D. These data have...

Multiwavelength observations of the supernova remnant G349.7+02 interacting with a molecular cloud

Author(s) : Lazendic, J. S. , Wardle, M. , Whiteoak, J. B. , Burton, M. G. , Green, A. J.
Description : We present molecular-line observations at millimetre, centimetre and infrared wavelengths of the region containing OH(1720 MHz) masers in the supernova remnant (SNR) G349.7+0.2, using the Australia Telescope (AT) Mopra antenna, the Swedish-ESO Submillimeter Telescope, the AT Compact Array and the ...

The interior of the SNR RX J0852.0-4622 (Vela Jr) at radio wavelengths

Author(s) : Reynoso, E. M. , Dubner, G. , Giacani, E. , Johnston, S. , Green, A. J.
Description : Aim: We observed the center of the supernova remnant Vela Jr in radio continuum in order to search for a counterpart to the compact central X-ray source CXOU J085201.4-461753, possibly a neutron star candidate which could be the remnant of the supernova explosion. Method: Observations were made wi...

H2O Maser Observations of Candidate Post-AGB Stars and Discovery of Three High-velocity Water Sources

Author(s) : Deacon, R. M. , Chapman, J. M. , Green, A. J. , Sevenster, M. N.
Description : We present the results of 22 GHz H_2O maser observations of a sample of 85 post-Asymptotic Giant Branch (post-AGB) candidate stars, selected on the basis of their OH 1612 MHz maser and far-infrared properties. All sources were observed with the Tidbinbilla 70-m radio telescope and 21 detections we...

Shock-Excited Maser Emission from Supernova Remnants: G32.8-0.1, G337.8-0.1, G346.6-0.2, and the HB3/W3 Complex

Author(s) : Koralesky, Barron , Frail, D. A. , Goss, W. M. , Claussen, M. J. , Green, A. J.
Description : We present the results of VLA observations in the ground-state hydroxyl (OH) transition at 1720 MHz toward 20 supernova remnants (SNRs). We detect compact emission from four objects. For three of these objects (G32.8-0.1, G337.8-0.1, and G346.6-0.2), we argue that the emission results from masers ...
