Milli-meter and Optical-Infrared Astronomical Observations by Using High-Level Overseas Telescopes.

五人(Toshinori Maihara、Humiide Iwamuro、Makoto Inoue、Takeshi Miyaji和Yukiyasu Kobayashi)参加了这个项目。T.Maihara和H.Iwamuro参观了茂纳基阿天文台，观察了高空大气中的OH气辉发射。这是日本和夏威夷大学合作研制的氢氧基抑制光谱仪(OHS)的前期准备工作。1992年2月7日至9日，他们在莫纳克亚山顶进行了红外光谱观测。到目前为止，还没有测量到1到2微米波长范围内的OH气辉。本文的观测是在UH2.2米望远镜上用空间减法成功地完成的，这使我们对OHS.M.有很大的希望。井上和T.Miyaji组合了JCMT(夏威夷)、SEST(智利)和OVRO(美国)三个站，在1 MM波长下进行了VLBI(甚长基线干涉仪)实验。这是第一个Exper…最大波长为1 mm，最高空间分辨率可达20微微秒。在检测到干涉图之前，我们不能确定是否成功。相关数据的简化将用一个正在建设中的新相关器进行。这一成功将使我们能够以惊人的分辨率进入活动星系核的最深处。小林对现代天文学的基础设施进行了调查。他参观了世界著名的天文台和研究所、皇家格林威治天文台、爱丁堡皇家天文台、慕尼黑Max Plank天体物理学研究所、Cerro Tololo美洲天文台、La Silla ESO天文台和Lick天文台。他参观了罗克韦尔科学中心，讨论了最先进的红外探测器和未来的发展前景。日本国家天文台的技术和管理基础都落后于天文学先进国家。他正在为日本纳天文台的基础设施建设制定总体规划。较少

Five persons (Toshinori Maihara, Humihide Iwamuro, Makoto Inoue, Takeshi Miyaji and Yukiyasu Kobayashi) were sent in this program.T. Maihara and H. Iwamuro visited Mauna Kea Observatory to observe OH airglow emission from the high altitude atmosphere. This is a preparative work for development of OH suppression spectrometer (OH suppressor, OHS), which will be commissioned as a collaborative instrument between Japan and University of Hawaii. They carried out infrared spectroscopic observations atop Mauna Kea from Februry 7 through 9, 1992. The OH airglow in the wavelength regions from 1 to 2 mum have never been measured so far. The present observations were successfully done by a spatially subtraction method on the UH2.2 m telescope, and made us feel strongly promising for the OHS.M. Inoue and T. Miyaji made an experiment of VLBI (Very Long Baseline Interferrometer) at a wavelength of lmm by combining three stations of JCMT (Hawaii), SEST (Chile), and OVRO (USA). This is the first exper … More iment at the wavelength of 1mm, capable of a highest spatial resolution of 20 mu usec. We are not sure of success until the interferogram can be detected. The data reduction of correlation will be made with a new correlator which is under construction. The success will enable us to get an access into the deepest core of active galactic nuclei with a remarkable resolution.Y. Kobayashi made survey of infrastructures for modern astronomy. He visited the world-wide famous observatories and institutes, Royal Greenwich Observatory, Royal Observatory of Edinburgh, Max Plank Institut fur Astrophysik, Munich, Cerro Tololo InterAmerican Observatory, La Silla ESO Observatory, and Lick Observatory. He visited Rockwell Science Center to discuss the most advanced infrared detectors and the future prospect on the development. The fundamentals of both technology and administration at National Astronomical Observatory, Japan, are behind the advanced countries in astronomy. He is building a master plan for establishment of infrastructures at Na Observatory, Japan. Less
