Study on the Activities and Interactions of Galaxies Based on the Observations at the Astronomical Observatories in Chile

1.Rho Ophiuchus分子云复合体(西田和T.Ichikawa)中合并星系的UBVRI测光和IRAS天体的光学识别1986年5月29日至31日，利用CTIO(Cerro Tolo美洲国家光学天体观测站)1.0米望远镜上的ASCAP(自动单通道口径光度计)进行了合并星系的UBVRI测光。1986年6月2日至6日，为了识别蛇夫座Rho Ophiuchus分子云复合体中具有IRAS点源的光学物体，利用Curtis/Schmidt望远镜进行了观测。2.类星体的深度测量(J.Jugaku)1986年11月25日至12月6日，在CTIO的Curtis/Schmidt望远镜上使用IIIaF平面对搜索类星体进行了深度测量观测。3.活动星系核和合并星系的近红外光谱(M.Nishi-da和Y.Taniguchi)1987年1月9日至13日，在CTIO的1.5米望远镜上用IRS(红外光谱仪)对具有活动星系核和星云的星系进行了近红外光谱测量。H_2v+1-0 S(1)2.12；亩；m；布莱克特；阿尔法；(4.05；u；>m)和(2.17；u；>m)；(Fe II)1.644；4.活动星系核和类星体的高色散谱(M.Iye)1987年6月20日至2月1日，利用拉西拉欧洲南方天文台2.2米望远镜上的Boller和Chivens光谱仪进行了活动星系核和类星体的高色散光谱测量。数据分析正在进行中。

1. UBVRI Photometry of Merging Galaxies and Optical Identifications of IRAS Objects in the Rho Ophiuchus Molecular Cloud Complex (M. Nishida and T. Ichikawa) From May 29 to 31, 1986, UBVRI photometry of merging galaxies was done by using ASCAP(Automated Single Channel Aperture Photometer) on the 1.0m telescope at CTIO (Cerro Tololo Inter-American Observatory, National Optical Astromy Observatories). From June 2 to 6, 1986, to identify the optical objects with the IRAS point sources in the Rho Ophiuchus molecular cloud complex, observations were done by using the Curtis/Schmidt telescope.2.Deep Survey of Quasars (J. Jugaku) From November 25 to December 6, 1986, deep survey observations to serach quasars were done using IIIaF planes on the Curtis/Schmidt telescope at CTIO. Analysis of the plates is in progress.3.Near Infrared Spectroscopy of Active Galactic Nuclei and Merging Galaxies (M. Nishi- da and Y. Taniguchi) From January 9 to 13, 1987, near infrared spectroscopy of galaxies with active galactic nuclei and starbrust nuclei was done by using IRS (Infrared Spectrometer) on the 1.5m telescope at CTIO. h_2 v+1-0 s(1) 2.12 <mu>m, Brackett <alpha>(4.05 <mu>m) and <delta> (2.17 <mu>m), and (Fe II) 1.644 <mu>m emission lines were measured.4.High-Dispersion Spectroscopy of Active Galactic Nuclei and Quasars (M. Iye) From Junuary 20 to February 1, 1987, the high-dispersion spectroscopy of active galactic nuclei and quasars was done by using Boller and Chivens Spectrograph on the 2.2m telescope at ESO(European Southern Observatory), La Silla. Analysis of the data is in progress.
