Abstract (from CDS):
We present Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) observations of submillimeter emissions from the NGC 6334 complex for both the 12[C<FONT SIZE="-2">I</FONT>]3P2 -> 3P1 fine-structure line of atomic carbon and the 12CO J = 4->3 rotational transition of CO. We detected strong 12[C<FONT SIZE="-2">I</FONT>]3P2 -> 3P1 emission from the entire star-forming NGC 6334 complex, and present maps of 12[C<FONT SIZE="-2">I</FONT>]3P2 -> 3P1 emission and 12CO J = 4->3 emission. Comparing these maps with archival ASCA data, we show that, to the south of NGC 6334, the [C<FONT SIZE="-2">I</FONT>] emissions are likely to be associated with strong X-ray emissions from the FIR sources. However, the calculation using the X-ray dissociation region model shows that the majority of the [C<FONT SIZE="-2">I</FONT>] emission can not arise from X-ray dissociation of the cloud. Alternatively, far-ultraviolet radiation produced in the photodissociation regions is expected to contribute to dissociate the carbon monoxide in the NGC 6334 complex.
