Far-infrared observations of three galactic star-forming regions: RCW 36, IRAS 10361-5830 and IRAS 10365-5803

Abstract

Three Southern star-forming regions-RCW 36, IRAS 10361-5830 and IRAS 10365-5803, have been observed simultaneously in two far-infrared bands with effective wavelengths of 58 micrometers and 150 micrometers using the Tata Institute of Fundamental Research (TIFR) 100 cm balloon-borne telescope. Intensity maps of these sources have been obtained covering areas of approximately 15 min × 20 min around each source, with an angular resolution of approximately 1.5 min. Multiple sources have been detected in each map. Luminosities and dust temperatures for individual sources have been derived. Data from IRAS Pointed Observations at 12, 25, 60 and 100 micrometers have been deconvolved to generate high resolution maps of these regions and these have been compared with our maps.
