SNR G18.8+0.3 data cubes

Continuing with the study of the surroundings of this SNR, we now focus on its southern border, which in the radio continuum emission shows a very peculiar morphology with a corrugated corner and a very flattened southern flank. We observed two regions toward the south of SNR G18.8+0.3 using the Atacama Submillimeter Telescope Experiment (ASTE) in the ^12^CO J=3-2.

One of these regions was also surveyed in ^13^ CO and C^18^O J=3-2. The angular and spectral resolution of these observations were 22" and 0.11km/s. We compared the CO emission to 20cm radio continuum maps obtained as part of the Multi-Array Galactic Plane Imaging Survey (MAGPIS) and 870um dust emission extracted from the APEX Telescope Large Area Survey of the Galaxy.
