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

本财政年度有9个党派的12人被派往国外。他们的活动和结果如下：利用IRTF，永田对银河系中心进行了红外成像，并发现了被HII区域包围的20个恒星群。数据缩减正在进行中。利用UKIRT， Hasegawa对银河系中心和NGC253进行了红外光谱分析，发现了H_2分子在紫外辐射场激发下的荧光发射。Nishida利用UKIRT对Seyfert 2星系和射电星系进行了红外光谱分析，并在Cyg a中探测到了H_2分子，这是首次在窄线射电星系中探测到H_2。Takami利用UH88对NGC253进行了红外分光光度测定，得到了星系的H_2O和CO指数，从而确定了星系的恒星组成。数据缩减正在进行中。Nishida利用KPN04m对IRAS23060+0505和Markarian 3进行了红外光谱分析。他通过对IRAS23060+0505中Pa α和Pa β宽翼发射谱线的检测，揭示了Seyfert I型核的存在。他还在马可福音3章中发现了H_2分子。Ogura和Nomaru利用AAT对L1641年的100个候选赫比格-哈罗天体进行了光谱学分析，其中20个天体已被确认为真正的赫比格-哈罗天体。利用AAT， Todo和Takato对H-H34进行了光谱学分析，并获得了物体上空的详细速度场。数据缩减正在进行中。Kawara和Taniguchi被授予在KPNO-4m上进行“裸1型塞弗特和类星的近红外H_2发射”的三个晚上。然而，这一场比赛完全是阴云密布，圆顶从未打开过。利用JCMT， Hayashi向H-H34和H-H111拍摄了CO 3-2图像。h - hl在分子发射和光学特征之间表现出显著的一致性，特别是在蓝移射流中。这种相关性描绘了原恒星活动与其环境之间强烈相互作用的区域。

Twelve persons in 9 parties have been dedicated abroad this fiscal year. Their activies and results are as follows :Using IRTF, Nagata has made infrared imaging toward the Galactic center and has found stellar cluster of 20 sources surrounded by HII region. Data reduction is in progress.Using UKIRT, Hasegawa has made infrared spectroscopy toward the Galactic center and NGC253 and has found fluorescent emission from H_2 molecule excited by UV radiation fields.Using UKIRT, Nishida has made infrared spectroscopy toward the Seyfert 2 galaxy and radio galaxy and has detected H_2 molecule from Cyg A. This is the first detection of H_2 from narrow-line radio galaxies.Using UH88, Takami has made infrared spectrophotometry of NGC253 and has obtained H_2O and CO index, which determine the stellar composition of the galaxies. Data reduction is in progress.Using KPN04m, Nishida has made infrared spectroscopy of IRAS23060+0505 and Markarian 3. He has revealed a presence of nucleus of Seyfert I type by detection of Pa alpha and Pa beta emission lines with broad wings in IRAS23060+0505. He has also detected H_2 molecules in Mark 3.Using AAT, Ogura and Nomaru have made optical spectroscopy of 100 candidates for Herbig-Haro objects in L1641, of which 20 objects have been confirmed as genuine Herbig-Haro objects.Using AAT, Todo and Takato have made optical spectroscopy toward H-H34 and obtained detailed velocity-fields over the object. Data reduction is in progress.Kawara and Taniguchi were awarded three nights on the KPNO-4m to carry out "Near infrared H_2 emission in Bare type 1 Seyferts and Quasars". This run was, however, entirely clouded out, the dome never being opened.Using JCMT, Hayashi has made CO 3-2 images toward H-H34 and H-H111. H-Hll shows a remarkable coincidence between the molecular emission and optical feature particularly in the blueshifted jet. This correlation delineates strongly interacting regions between the protostellar activity and its environment.
