Description:
We present the first results obtained with our new imaging Fabry-Perot spectrometer, KWIC. We obtained a fully sampled 9.8 sec. spatial resolution image of the inner 8 min. x 12 min. region of the Orion Nebula in the 37 micro m continuum and a somewhat smaller scale image in the (SiII) 35 micro m line. The continuum image traces out the structure of the interface region between the molecular cloud and the Orion A HII region, as well picking out embedded sources such as the BN-KL star cluster. The continuum directly yields the luminosity of the sources and is used to deduce dust mass and grain parameters. Our (SiII) image both reveals the clumpy structure of the interface region and signals the presence of a dissociative J-shock in the high velocity outflow from IRc2.
