We have carried out hydrogen Paschen-α(1.87μm) narrow-band imaging observations of the Galactic Plane and 41 nearby starburst galaxies, utilizing the near-infrared camera ANIR installed on the miniTAO 1m telescope. As the miniTAO is located at the summit of Co. Chajnantor with extremely high altitude of 5640m, it enables us to carry out observations of Pa-α emission from the ground, which is otherwise very difficult. We obtained new insights into the galaxy formation and evolution that (1) the dispersion known in the Kennicutt-Schimdt law (the correlation between molecular gas masses and star-formation rates) seems to be dependent on the age of star forming regions, and that (2) there may be a previously unknown star-forming mode in the starburst activities of galaxies.

我们利用安装在miniTAO 1 m望远镜上的近红外照相机ANIR对银道面和41个邻近星暴星系进行了氢Paschen-α（1.87μm）窄带成像观测。由于miniTAO位于Chajnantor山顶，海拔5640米，使我们能够从地面进行Pa-α发射的观测，这是非常困难的。对星系的形成和演化有了新的认识：（1）Kennicutt-Schimdt定律（分子气体质量与恒星形成速率之间的相关性）中已知的色散似乎依赖于星星形成区的年龄;（2）在星系的星暴活动中可能存在一种以前未知的恒星形成模式。
