Dr.Wakamatsu made observations with a multi-object spectograph of the 48-inch Schmidt telecope at Anglo Australia Observatory, in order to detect wall structures between Ophiuchus super cluster of galaxies and Hercules one.High quality spectrum of more than five hundred galaxies were obtained by the present observations.A sign of wall structure perpendicular to a local super cluster plane was detected.Dr.Ichikawa and Mr.Honma observed several distant galaxies in 10,000-20,000 km/s red shift velocities using a high spatical resolution CCD camera SIS mounted on Canada-France-Hawaii telescope at Mouna Kea in the US.They obtained V,R,I images of five galaxies.From the present data and Nobeyama's CO emission data, the distance of the galaxies and the Hubble constant were obtained.Dr.Baba conducted observations of Be binary stars at the San Pedro Martir Observatory in Mexico.Their developed speckle spectroscopic camera was attached to the Cassegrain focus of the 2.1m telescope.Some of the ob … More served Be binaries will be spatially separated and analyzed spectroscopically.They also conducted observations of widely separated binaries and have shown that a widely separated staris are usable for high-resolution Shift-and-Add imaging as a reference.In collaboration with the Carnegie Institution, Drs.Kashikawa and Sekiguchi observed clusters of galaxies in BVR three color banks, using their mosaic CCD camera (4000x7000pixels) with a telescope at Las Campnas observatory.They found a significat difference in the luminosity function in the faint regions of these clusters.This difference is mostly due to dwarf galaxies.They are doing further data analysis and preparing articles.Dr.Tamura and Mr.Murakawa have conducted near-infrared spectroscopic surveys of background and embedded stars toward the Taurus dark cloud with using the prism array spectrometer (PASP2) on the University of Wyoming 2.3m telescope and on the Mount Lemmon 1.5m telescope.The great number of the sample has enabled us to determine in detail the distribution of ice-band features at 3 micron within the cloud.Furthermore, important information on the growth of ice mantle within dark clouds and circum stellar environments.Dr.Sugai flew twice to the United States in order to carry out near-infrared spectroscopic observations of starburst galaxies by using Lick 3-m telescope.Near-infrared observations are useful for understanding their activities.He observed starburst galaxies in a wide range of wavelengths by using a double-beamed camera.The data of about ten observed galaxiesI are being reduced.The emission mechanisms seem to vary drastically among galaxies.This kind of decompositions will enable us to understand the origin and evolution of starbursts.Dr.Yamada made an observation with near-infrared camera QUIRC attached to the University of Hawaii 2.2m telescope at Mauna Kea Observatory (U.S.A.) to identify a distant cluster of galaxies around a quasar at z=1.1.At this redshift the optical-NIR color of elliptical galaxies, which constitute clusters, are observed very red.By using this nature he is trying to identify a cluster at the region where enhancement of galaxy surface density has already been detected in deep optical image.He could obtain reasonably good data and data-analysis is in progress now.Dr.Sugitani used CTIO 1.5m telescope with CIRIM to survey 45 bright-rimmed clouds with IRAS point sources for evidence of triggered star formation in/aroundOb associations of the southern sky.He has completed 70% of JHK imagingfor these objects and found many clusters of low-mass or intermediate-massstars which are considered to be forme due to the triggering by UV formthe OB associations.

若松博士在英澳天文台用48英寸施密特望远镜的多物体光谱仪进行了观测，为了探测蛇夫座超星系团和武仙座超星系团之间的壁结构，我们观测了500多个星系的高质量光谱，发现了垂直于局部超星系团平面的壁结构迹象。市川博士和本间先生观测了几个远距离的利用安装在美国MounaKea的加拿大-法国-夏威夷望远镜上的高空间分辨率CCD相机SIS，对5个星系进行了10，000 - 20，000 km/s红移速度的V，R，I观测，获得了5个星系的V，R，I图像。巴巴博士在年的圣佩德罗马蒂尔天文台对Be双星进行了观测。墨西哥。他们开发的斑点光谱照相机被安装在2.1米望远镜的卡塞格伦焦点上。 ...更多信息 服务Be二进制将空间分离和光谱分析。他们还进行了广泛分离的二进制观测，并表明广泛分离的恒星可用于高分辨率的平移和添加成像作为参考。在与卡内基研究所合作，博士。Kashikawa和Sekiguchi观察星系团在BVR三色银行，用他们的镶嵌CCD摄像机（4000 x7000像素）他们用Las Campnas天文台的一架望远镜进行了观测。他们发现这些星团的暗区光度函数存在显著差异。这种差异主要是由于矮星系。他们正在做进一步的数据分析和准备文章。田村博士和村川先生进行了用怀俄明州大学2.3米望远镜和莱蒙山1.5米望远镜的棱镜阵列光谱仪（PASP-2）对金牛座暗星云的背景星和嵌入星进行了近红外光谱测量。大量的样品使我们能够详细地确定星云内3微米处冰带特征的分布。此外，Sugai博士曾两次飞往美国，利用Lick 3-m望远镜对星暴星系进行近红外光谱观测。近红外光谱观测的结果表明，近红外光谱的观测结果与星云和恒星周围环境中冰幔的生长有关。红外线观测对了解它们的活动很有用。他用双波长望远镜在很宽的波长范围内观测了星暴星系，Yamada博士在2002年10月11日的一项研究中，利用一架光束照相机，对大约十个观测到的星系I的数据进行了分解。星系之间的发射机制似乎有很大的差异。这种分解将使我们能够了解恒星暴的起源和演化。Yamada博士在2002年11月11日的一项研究中，在莫纳克亚天文台（美国），用夏威夷大学2.2米望远镜上的近红外相机QUIRC进行了观测。以确定一个z= 1.1的类星体周围的遥远星系团。在这个红移处，构成星系团的椭圆星系的光学近红外颜色，通过利用这种性质，他试图在已经在深光学图像中检测到星系表面密度增强的区域识别一个星系团。他可以获得相当好的数据和数据-分析工作正在进行中。杉谷博士使用CTIO 1.5米望远镜和CIRIM，用IRAS点源观测了45个亮边云，以寻找南天Ob星协内或周围触发星星形成的证据。他已经完成了这些天体70%的JHK成像，并发现了许多低质量或中等质量的星团。被认为是由于紫外线的触发而形成的质量星形成了OB星协。少
