dc.description.abstractEnWe report the first sub-arc second (0.65" x 0.51") image of the dimethyl ether (CH3)2O molecule toward the Orion Kleinmann-Low nebula (Orion--KL). The observations have been carried at 43.4 GHz with the Expanded Very Large Array (EVLA). The distribution of the lower energy transition 6(1,5) - 6(0,6), EE; Eu = 21K mapped in this study is in excellent agreement with the published dimethyl ether and methyl formate emission images obtained with a lower resolution. The main emission peaks are observed toward the Compact Ridge and Hot Core southwest components, as the northern parts of the Compact Ridge and in an intermediate position between the Compact Ridge and the Hot Core. Our study shows that higher spectral resolution (WIDAR correlator) and increased spectral coverage provided by the EVLA offer new possibilities for imaging complex molecular species. The sensitivity improvement and the other EVLA improvements make this instrument well suited for high sensitivity, high angular resolution, molecular line imaging.
