Outline of Final Research Achievements

In order to understand the formation mechanism of massive stars, we aim to obtain far-infrared wide-area mapping data of massive star-forming regions in the [CII] emission, which is the strongest cooling line of gas in photo-dissociation regions. We first refurbished the existing [CII] spectrometer to improve the cooling and optical performance. We also developed the ground support equipment to test the spectrometer. Then we shipped the instrument to India and performed balloon-borne observations at Hyderabad Balloon Facility of the Tata Institute of Fundamental Research (TIFR). As a result, we have successfully carried out balloon observations twice (Nov 2017 and Mar 2018), and obtained the [CII] mapping data of 9 massive star-forming regions. In parallel to the observations, we have also developed a new far-infrared Ge:Ga BIB array detector of a 5 x 5 pixel format and a high-resolution Fabry-Perot spectrometer to integrate them to a new instrument for balloon observations.
