Abstract:
We present 12mm Mopra observations of dense molecular gas towards the
W28 supernova remnant (SNR) field. The focus is on the dense molecular
gas towards the TeV gamma-ray sources detected by the HESS telescopes,
which likely trace the cosmic rays from W28 and possibly other sources
in the region. Using the NH3 inversion transitions we reveal several
dense cores inside the molecular clouds,
Description:
Observations were carried out on the Mopra radio telescope in May/June
of 2008 and April of 2009 employing the Mopra spectrometer (MOPS) in
zoom-mode.

Note (1): For Core 4, for NH3 lines, parameters are taken from the mapping data.
Note (2): * when the close rest frequencies of HC5N(10-9) and H89γ lead
to their cross-contamination (see online Figure B5).
