Bulk Motion of the Local Universe due to Ophiuchus Supercluster

在这两年中，我们在局部宇宙体运动的观测研究方面取得了重大进展。从2001年6月开始，在澳大利亚赛丁泉天文台使用英国施密特望远镜的新型多目标光纤摄谱仪，对整个南方天空进行红移观测项目已准备就绪。我们的研究总结如下：1)确定了10万多个比k13.7等亮的星系的红移观测策略，以研究局部宇宙的整体运动观测宇宙学。2)基于j.h hchra教授的2微米质量观测，编制了一份Ohiuchus区域的星系表。3)通过比较我们自己的基于SERC-J调查的列表和Huchra的列表，他们的光学位置足够精确，可以在目标星系上放置光纤。4)多目标光纤光谱仪已于2月下旬调试成功，正在进行最后调整，准备稳定使用。5)我们对蛇夫座区域的观测计划安排在7月13-18日。

During these two years, we made a big progress on observational study of bulk motion of the Local Universe. Observing project for redshift survey in all the southern sky are ready to start from June in 2001 : with a new multi-object fiber spectrograph of UK Schmidt telescope at Siding Spring Obseervatory in Australia. Summary of our research is given bellow :1) Stratagy of redshift survey has been fixed for a sample of more than 100,000 galaxies brighter than K 13.7 mag. to study on observational cosmology regarding on bulk motion of the Local Universe.2) A list of galaxies in the Ohiuchus region was prepared based on 2 micron MASS survey by Prof.J.Huchra.3) By comparing our own list based on SERC-J Survey with Huchra's, their optical positions are precise enough to put fibers on the target galaxies.4) Commissioning of the multi-object fiber spectrograph was successfully made in late Febuary, and are in final adjustment for steady use.5) Our observing proposal for Ophiuchus region has been scheduled on July 13-18.
