高分辨率的星系冷气体观测对于星系恒星形成过程的研究至关重要。为了研究不同恒星形成效率 (Star formation efficiency, SFE = SFR/M_gas) 的星系空间分辨性质，本项目计划借助申请人申请到的高优先级ALMA,APEX, Magellan, VLT/MUSE数据(于2018年观测)和已经观测完成的ALMA, APEX/SEPIA数据研究Herschel远红外观测样本里的一批红移约0.15的星系恒星形成效率，星系的H2气体和电离气体的分布，星系恒星形成和星系动力学的关系，不同恒星形成效率的星系金属丰度，星系气体电离源等一系列课题。

High-resolution observations about the cold gas component in the galaxies are crucially important in understanding the process of the star formation. To investigate the spatial properties of the galaxies with different star formation efficiency (SFE = SFR/M_gas), based on the ALMA, APEX, Magellan, VLT/MUSE data that we have been awarded and the ALMA, APEX data that have delivered, we propose to study the transition of the star formation efficiency, the spatial distribution of the H2 gas and ionized gas, the relation between the star formation and galactic dynamics, the metallicity and the ionization source of the galaxy with different SFE on a Herschel selected galaxy sample at redshift 0.15.
