Abstract

A summary of results from a 7 mm-wavelength survey towards the young X-ray and γ-ray-bright supernova remnant, RXJ1713.7-3946 (SNR G347.3-0.5) is presented. Using the Mopra telescope, the high critical density tracer CS(1-0) was targeted, complementing previous Nanten2 molecular gas studies of CO transitions. In hadronic γ-ray emission scenarios (p-p interactions), the mass of cosmic ray target material available is an important factor, so we estimate the mass of dense gas towards RX J1713.7-3946. Also of interest was the shock-tracing molecule, SiO. Although there was no evidence of SiO emission physically excited by the RXJ1713.7-3946 shock, a chance-discovery of vibrationallyexcited SiO(1-0) emission is likely to be a maser that is associated with an evolved star.
