Dr.Oishi used the 12m radiotelescope of NRAO and surveyed CH3NH2 in massive star forming regions. He found through mapping observations that CH3NH2 concentrates at the central Hll regions in SgrB2. He also used the 15m radio telescope of SEST and mapped the SgrB2 region in the J=2-1 and J=3-2 transitions. He also observed the J=5-4 transition in 12 positions where SiO emission is intense.Dr.Ohta observed the quasar BR1202-0725 which is considered to be a forming galaxy at z=4.7 in CO(J=2-1) line using the NRAO VLA aiming at revealing a physical state and distribution of the gas. Unfortunately the weather was very bad and we could not detect the emission line.Dr.Kawabe observed CO(J=2-1) line and 8 GHz continuum emission from one of the high est-redshift quasars, BR1202-075, which is thought to be a candidate protogalaxy, using Very Large Array (VLA) in National Radio Astronomy Observatory (NRAO). He could not detect CO(2-1), however found a new high-z galaxy candidate in the observing … More field of the 8 GHz observations.Dr.Baba conducted speckle spectroscopic observations of alpha Ori, omicron Cet, omicron And, 28Tau, etc. with 2.1m reflector of the San Pedro Martir Observatory in Mexico. The introduction of an active support system for the primary mirror led us to obtain good-quality data.Prof.Hidai observed high-dispersion spectra of 4 quasars with the HIRES equipped on the 10m Keck telescope. Because of rather poor weather, S/N ratios of data are not so high. The data of Ly-alpha forests and damped Ly-alpha systems are now being analyzed.Dr.Shibata have made multifrequency VLBI observations of megamaser source NGC3079 using VLBA.We investigate the gas structure near the nucleus of the galaxy with the 4.1,8,15 and 22 GHz continuum, water masers and HI absorption results.Dr.Onaka have have made observations of the mid-infrared spectra of about 30 late-type stars by the Mid-Infrared Camera & Spectrometer with two telescopes of the Mt. Lemmon Obsevatory.Dr.Sugai carried out Near-infrared line observations of interacting/merging galaxies by using a Fabry-Perot mounted on UKIRT.Because of the bad weather, he was able to observe effectively one night, out of three granted nights.Dr.Hayashi have carried out a high resolution mapping of the near-infrared spectral line of molecular hydrogen to probe the shocked structure induced by such a strong interaction.Dr.Yamashita observed several active galaxies with mid-infrared spectrograph and found that many of these active galaxies have much more flux than it has been expected.

大石博士使用了NRAO的12米射电望远镜，在大质量星星形成区调查了CH 3 NH 2。他通过测绘观测发现，CH 3 NH 2集中在SgrB 2的中央H11区域。他还使用SEST的15米射电望远镜，绘制了J=2-1和J=3-2跃迁的SgrB 2区域。Ohta博士利用NRAO VLA观测了被认为是形成中星系的类星体BR 1202 -0725的CO（J=2-1）线z=4.7，旨在揭示气体的物理状态和分布。Kawabe博士利用美国国家射电天文台（NRAO）的甚大阵（VLA）观测到了被认为是原星系候选者的最高红移类星体BR 1202 -075的CO（J=2-1）谱线和8 GHz连续谱线。他无法探测到CO（2-1），但在观测中发现了一个新的高z星系候选者。 ...更多信息 巴巴博士用墨西哥圣佩德罗马蒂尔天文台的2.1米反射镜对猎户座α星、奥米克隆星Cet、奥米克隆星And、28头星等进行了散斑光谱观测。通过对主镜主动支撑系统的引入，我们获得了高质量的数据。Hidai教授使用10米凯克望远镜上的HIRES观测了4个类星体的高色散光谱。由于天气条件较差，资料的信噪比不高。柴田博士利用VLBA对超脉泽源NGC 3079进行了多频VLBI观测，在4.1，8，15和22 GHz连续谱上研究了星系核附近的气体结构。水脉泽和HI吸收的结果。Onaka博士用中红外照相机&光谱仪与两个望远镜的山。莱蒙观测站。菅井博士使用安装在UKIRT上的法布里-珀罗望远镜对相互作用/合并的星系进行了近红外线观测。由于天气恶劣，他在一个晚上进行了有效的观测，Hayashi博士已经完成了一个高分辨率的近-红外光谱线的分子氢探测冲击结构引起的这种强烈的相互作用。山下博士观察了几个活跃的星系，中红外光谱仪，发现许多这些活跃的星系有更多的流量比预期的。少
