Study of floculent spiral galaxies with polarimetric imaging from visible to nea-rinfrared wavelengths

我们用UH88和UKIRT望远镜对四个外部星系和银河系平面深处进行了观测，总结了这三年的活动；1999年，在UH88进行了4月的测试观测，5月运往莫纳克亚，6月在UH88进行了4个晚上的成像观测，8月安装了光谱模式，9月在UH88进行了3个晚上的光谱观测，12月安装了偏振模式，1月份在UKIRT进行了偏振观测。2000年8月、1月和3月，总共3次在UKIRT进行了偏振观测。2001年，TRISPEC于5月返回名古屋，探索了光学和红外波段之间“瞳孔”不匹配的缺陷的根源。我们发现LiF透镜的光轴偏离机械中心2 mm，发表了中谷英彦和渡边真彦的一篇参考论文和两篇博士论文，以及三年来在TRISPEC项目中发表的两篇山崎俊志和山中裕介的硕士论文。我相信这对于学习人力资源和基本仪器的各种发展风格是很重要的，我们已经为制造水晶透镜做出了贡献。

We carried out observations of four external galaxies and, depths of our Galactic plane with TRISPEC on UH88 and UKIRT telescopes atop Mauna Kea.We summarize the activities for these three years ;In 1999, test observations in April at Mitaka, shipping to Mauna Kea in May, imaging observation at UH88 for 4 nights in June, install the spectroscopic mode in August, spectroscopic observation at UH88 for 3 nights in September, install the polarimetric mode in December, and polarimetric observation in January at UKIRT.In 2000, in August, Januray and March, three times in total, polarimetric observations at UKIRT.In 2001, returned TRISPEC to Nagoya in May and searched the origin of the flaws of mismatch of "pupils" between optical and infrared bands. We found the mis-alignment of optical axis by 2 mm from the mechanical center for the LiF lens.We published one refereed paper and two Ph.D. thesis by Hidehiko Nakaya and Makoto Watanabe, and two Master thesis by Atsushi Yamazaki and Yusuke Yamanaka from the TRISPEC project for these three years. I believe that it was important for learning various styles of developments both for human resources and basic instruments, and we have contiributed to manufacturing the crystal lenses.
