High-resolution H I and radio continuum observations of the SNR G290.1-0.8

We have observed the supernova remnant (SNR) G290.1-0.8 in the 21-cm H i line and the 20-cm radio continuum using the Australia Telescope Compact Array (ATCA). The H i data were combined with data from the Southern Galactic Plane Survey to recover the shortest spatial frequencies. In contrast, H i a...
