Environs of Bilateral Supernova Remnants with Neutron Stars
G. Dubner, E. Giacani, B. M. Gaensler +2
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…
Detection of HI 21 cm-line absorption in the Warm Neutral Medium and in the Outer Arm of the Galaxy
K. S. Dwarakanath, C. L. Carilli, W. M. Goss
Using the Westerbork Synthesis Radio Telescope, we have detected HI 21 cm-line absorption in the Warm Neutral Medium of the Galaxy toward the extragalactic source 3C147. This absor…
The Interstellar Medium around the Supernova Remnant G320.4-1.2
G. M. Dubner, B. M. Gaensler, E. B. Giacani +2
Using the Australia Telescope Compact Array, we have carried out a survey of the HI emission in the direction of the ``barrel-shaped'' supernova remnant (SNR) G320.4-1.2 (MSH 15-52…
The Radio Recovery of SN 1970G: The Continuing Radio Evolution of SN 1970G
Christopher J. Stockdale, W. M. Goss, John J. Cowan +1
Using the Very Large Array, we have detected radio emission from the site of SN 1970G in the Sc galaxy M101. These observations are 31 years after the supernova event, making SN 19…
VLA Observations of the H92alpha line from NGC 5253 and Henize 2-10 : Ionized Gas around Super Star Clusters
Niruj R. Mohan, K. R. Anantharamaiah, W. M. Goss
We have detected the H92alpha radio recombination line from two dwarf starburst galaxies, NGC 5253 and He 2-10, using the Very Large Array. Both the line data as well as the radio…
Interstellar Medium Surrounding the WO Star in the Galaxy IC 1613: New Optical and Radio Observations
T. A. Lozinskaya, A. V. Moiseev, V. L. Afanasiev +2
Observations of the nebula S3 associated with the WO star in the galaxy IC 1613 and of an extended region surrounding S3 are reported. The star and bright core of the nebula were o…
VLA Detection of the Ionized Stellar Winds Arising from Massive Stars in the Galactic Center Arches Cluster
Cornelia C. Lang, W. M. Goss, Luis F. Rodriguez
The Galactic center Arches stellar cluster, detected and studied until now only in the near-infrared, is comprised of at least one hundred massive (M>20 Msun) stars. Here we report…
Pulsar wind nebulae around the southern pulsars PSR B1643-43 and PSR B1706-44
E. Giacani, D. A. Frail, W. M. Goss +1
We present high resolution VLA images taken at the wavelengths of lambda 20 cm, lambda 6 cm, and lambda 3.6 cm in the vicinity of the pulsars PSR B1706-44 (PSR J1709-4428) and PSR…
A VLA H92alpha Study of the Arched Filament Complex Near the Galactic Center
Cornelia C. Lang, W. M. Goss, Mark Morris
The VLA has been used at 8.3 GHz in the DnC and CnB array configurations to carry out an H92alpha recombination line study (at 8.3 GHz) of the ionized gas in the Arched Filaments H…
Australia Telescope Compact Array Observations of the OH Star Roberts 22: Resolved Images of OH Emission
Kristy Dyer, W. Miller Goss, Athol Kemball
We have imaged the unusual OH/IR object G 284-0.8 (Roberts 22) in the OH transitions at 1612, 1665 and 1667 MHz using the Australia Telescope Compact Array in Narrabri, NSW, Austra…
