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

我们在莫纳克亚山上的UH88和UKIRT望远镜上使用TRISPEC观测了四个外部星系和银河系平面的深度。我们总结了这三年的活动；1999年4月在Mitaka进行试验观测，5月运到Mauna Kea， 6月在UH88进行4晚成像观测，8月安装光谱模式，9月在UH88进行3晚光谱观测，12月安装偏振模式，1月在UKIRT进行偏振观测。2000年8月、1月和3月，UKIRT共进行了三次极化观测。2001年5月，将TRISPEC送回名古屋，寻找光学波段与红外波段“瞳孔”不匹配缺陷的根源。我们发现LiF镜头的光轴偏离机械中心2mm。在TRISPEC项目中，我们发表了中谷英彦和渡边诚的论文1篇，博士论文2篇，山崎敦和山中佑介的硕士论文2篇。我认为这对于学习人力资源和基本仪器的各种发展风格很重要，我们为制造水晶镜片做出了贡献。

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.
