| Outline of Final Research Achievements |
The main goal of this project is to develop and install a new receiver system on ASTE telescope in order to observe the CO(4-3) and CO(3-2) emissions in a sample of Luminous Infrared Galaxies. The data is used to investigate the relationship between moderately dense gas and star formation/AGN activities seen in these colliding galaxy systems. The development and implementation of the new receiver were carried out according to the original plan, and the technical specifications were met. A pre-survey of 26 galaxy was successful, and we found a new correlation between star formation efficiency and galaxy interaction stage. In addition, new data toward a late stage Luminous Infrared Galaxy NGC3256 suggests evidence for dense gas outflows. While these pre-surveys were successful, the main survey which targets 103 sources suffered from instrumental problems of the ASTE telescope and unfortunate poor weather conditions, and hence we could not complete the survey as was designed originally.
