项目摘要

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.

Oishi博士使用了NRAO的12m辐射镜，并在大型恒星形成区域进行了调查。他通过映射观察发现CH3NH2集中在SGRB2中的中央HLL区域。他还使用了1500万射电望远镜，并在J = 2-1和J = 3-2的过渡中绘制了SGRB2区域。他还观察到J = 5-4的跃迁在12个位置，其中SIO发射强烈。不幸的是，天气非常糟糕，我们无法检测到排放线。Dr.Dr.kawabe观察到的CO（J = 2-1）线和8 GHz连续性从高EST-REDSHIFT类星体之一，BR1202-075发出，它被认为是候选人，使用了非常大的Array（VLA）在国家无线电台Astronomy Perservorate（NRARAO）中（NRARAO）。他无法检测到CO（2-1），但是在观察中发现了一个新的High-Z Galaxy候选者……更多的8 GHz观测领域。Dr.Baba对Alpha Ori，Omicron Cet，Omicron，Omicron和28tau等进行了斑点光谱观测，并具有2.1m的Sande Pedro Martir Martir观察者。引入主要镜子的主动支持系统使我们获得了优质数据。由于天气差，数据的S/N比不那么高。现在正在分析Ly-Alpha森林和该死的Ly-Alpha系统的数据。Dr.shibata使用VLBA对Megamaser Source NGC3079进行了多频率VLBI观察。我们使用VLBA进行了研究。我们研究了Galaxy核附近的气体结构，并以4.1,15,8,15和22 GHZ Conterum，Wateruum Massers和Hi Massers和Hi Massers和Hi。中型摄像机和光谱仪中的大约30颗晚期型星星中的中红外光谱，带有两个lemmon山的望远镜望远镜，苏格（Sugai对分子氢的近红外光谱线进行了高分辨率映射，以探测如此强烈的相互作用引起的冲击结构。Dr.Yamashita观察到了几个具有中红外光谱仪的活性星系，发现许多这些活性星系具有比预期的磁通量要多得多。
