Milimeter and Optical-Infrared Astronomical Observations by Using High-level Overseas Telescopes

大石博士使用NRAO的12米射电望远镜，在大质量恒星形成区探测了CH3NH2。他通过测绘观测发现，CH3NH2集中在SgrB2的中心H11区域。他还使用了SEST的15米射电望远镜，绘制了J=2-1和J=3-2跃迁中的SgrB2区域。他还在12个SiO发射强烈的位置观测到了J=5-4跃迁。Ohta博士利用NRAO VLA观测了类星体BR1202-0725，该星系在CO(J=2-1)线上被认为是一个z=4.7的形成星系，目的是揭示气体的物理状态和分布。不幸的是，天气非常恶劣，我们无法探测到发射线。川部博士利用国家射电天文台(NRAO)的甚大阵列(VLA)观测到了红移最高的类星体之一BR1202-075的CO(J=2-1)线和8 GHz连续辐射。他没有探测到CO(2-1)，但在观测…中发现了一个新的高z星系候选者巴巴博士使用墨西哥圣佩德罗火星天文台的2.1米反射镜对阿尔法ORI、奥米克龙CET、奥米克龙和28Tau等进行了散斑光谱观测。主镜主动支撑系统的引入使我们获得了高质量的数据。Hidai教授用10米Keck望远镜上的HIRE观测了4个类星体的高色散谱。由于天气比较恶劣，S/N的数据没有那么高。柴田博士利用VLBA对超脉冲源NGC3079进行了多频VLBI观测，利用4.1 GHz、8 GHz、15 GHz和22 GHz的连续谱、水脉泽和HI吸收结果研究了星系核附近的气体结构。Onaka博士用中红外相机和光谱仪对大约30颗晚型恒星的中红外光谱进行了观测。柠檬天文台。Sugai博士使用安装在UKIRT上的Fabry-Perot对相互作用/合并的星系进行了近红外线观测。由于恶劣的天气，他能够有效地观察到三个夜晚中的一个。Hayashi博士进行了分子氢的近红外光谱线的高分辨率绘制，以探测由如此强烈的相互作用引起的冲击结构。山下博士用中红外光谱仪观察了几个活跃星系，发现其中许多活跃星系的通量比预期的要大得多。较少

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.
