European Southern Observatory (2007)
John R. Dickel, You-hua Chu, Christopher Gelino, Ross Beyer, Michael J. Burton, D. K. Milne, ...
Received; accepted Radio, near-infrared, and Hff images of the supernova remnant N49 in the LMC show a filamentary shell structure, characteristic of remnants at the adiabatic point-blast phase of...
Radio Spectral Index Variations and Physical conditions in Kepler's Supernova Remnant (2002)
DeLaney, Tracey, Koralesky, Barron, Rudnick, Lawrence, Dickel, John R.
A new epoch of VLA measurements of Kepler's supernova remnant was obtained to make accurate measurements of the radio spectral index variations and polarization. We have compared these new radio...
A Peculiar Linear Radio Feature in the Supernova Remnant N206 (2002)
Klinger, Robert J., Dickel, John R., Fields, Brian D., Milne, Douglas K.
We present images of the supernova remnant N206 in the LMC, taken with ATCA at wavelengths of 3 and 6 cm. Based on our data and previously published flux densities, the spectral index of N206 is...
The Crab-like Supernova Remnant G21.5-0.9 at Millimeter Wavelengths (2001)
Bock, Douglas C. -J., Wright, Melvyn C. H., Dickel, John R.
We present a BIMA image of the supernova remnant G21.5-0.9 at 94 GHz with angular resolution 8.6" x 4.5". On scales larger than our synthesized beam, our results do not indicate any radial or local...
The Radio Structure of the Supernova Remnant MSH14-63 (2000)
Dickel, John R., Strom, Richard G., Milne, D. K.
G315.4-2.3 is an extended shell supernova remnant (SNR) with some characteristics of evolutionarily young remnants and some of older ones. To further elucidate some of its characteristics, we present...
Supernova Remnants in the Magellanic Clouds III: An X-ray Atlas of LMC Supernova Remnants (1999)
Williams, Rosa Murphy, Chu, You-Hua, Dickel, John R., Petre, Robert, Smith, R. Chris, Tavarez, Maritza
We have used archival ROSAT data to present X-ray images of thirty-one supernova remnants (SNRs) in the Large Magellanic Cloud (LMC). We have classified these remnants according to their X-ray...
