The MSX Galactic Plane Survey Submillimeter Results
Published online by Cambridge University Press: 25 September 2002
Abstract
The MidCourse Space eXperiment (MSX) surveyed the Galactic plane within 5° latitude in four mid-infrared spectral bands. A set of full resolution (20'') 1.5°×1.5° images on 6'' pixel centers has been created in each spectral band by co-adding all the survey data. A lower (1.2') resolution atlas of 10°×10° images provide large-scale panoramas of the plane. A new class of objects has been identified in the images, infrared dark clouds, which are silhouetted against the mid-infrared background emission from the interstellar medium in the Galactic plane. The IRAS ISSA plates indicate that these clouds are dark out to 100 μm. Submillimeter emission traces the form of the dark cloud and reveals cores indicative of class 0 protostars.
