| JCMT/SCUBA Sub-Millimeter Wavelength Imaging of the Integral Shaped Filament in Orion (2007) | |||||||||||||
Abstract | |||||||||||||
| We present the first high dynamic range and sensitivity images of the sub-millimeter wavelength continuum emission at 450m and 850m of the "Integral Shaped Filament" in the northern portion of the Orion A cloud which contains the nearest site of on-going high-mass star formation. The images trace the morphology and spectral index of optically thin emission from interstellar dust and constrain the grain temperature and emissivity. The images reveal a remarkable chain of compact sources embedded in a narrow (! 1 0 = 0.14 pc) high column density filament that extends over the 50 0 (7 pc) length of the map with faint extended structure surrounding it. While many compact sources contain extremely young protostars, others may be pre-collapse phase cloud cores. The brightest region, associated with OMC1, contains a remarkable group of dust filaments radiating radially away from this high luminosity core that coincide with filaments of NH 3 emission. The spectral index is uniform... | |||||||||||||
