Abstract:
In a previous paper we investigated the molecular environment toward
the eastern border of the supernova remnant (SNR) G18.8+0.3.
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
12CO J=3-2. One of these regions was also surveyed in 13 CO and
C18O 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.
Description:
The observations of the molecular lines were carried out between
September 7 and 13, 2013 with the 10m Atacama Submillimeter Telescope
Experiment (ASTE). We used the CATS345 receiver, which is a two-single
band SIS receiver remotely tunable in the LO frequency range of
324-372GHz.
