项目摘要

The proposed investigation was very fruitful and we could obtain various important results in understanding the galaxy formation and its relation to the quasar activity.Especially, we have conducted rather systematic deep near-infrared observation of the clusters at z>1 using the Subaru Telescope as well as some foreign facilities such as APO 3.5m and CFHT and revealed the photometric and clustering properties of the relatively young galaxies in the environment of dynamically young clusters. For the study of the proto-typical high-z cluster in the field of radio galaxy 3C 324, we published three papers as ones of the first scientific outputs from the Subaru telescope in 1999. In 2000, we expanded the study using the newly analyzed optical data obtained with the Subaru telescope. We have found that (i) widely distributed colors in hjgh-redshift clusters which implies the various different star-formation history among the cluster galaxies, and (ii) the luminosity and color segregation ehich suggest the "biased" formation of the galaxies. We also published the results of the study of the supercluster-scale clustering of faint red galaxies in the region of B2 1336+28. Further, in the region of the candidate proto-cluster 53W002 at z=2.4, we obtained the deep near-infrared image with the Subaruand found that (i) the emission-line galaxies clutered in this region are faint in near-infrared and they are revealed to be low-mass young star-burst galaxies, and (ii) few well developed quiescent galaxies are seen in this region.We also have some interesting results for the quasar hosts and their relation with the galaxy formation. Besides the study on the host of 3C324 mentioned above, (i) we published a paper for high-z type-2 quasar, (ii) we proceeded the optical follow-up of the ASCA surveys, and (iii) we are conducting the Subaru/XMM Deep surveys.

这项研究成果丰硕，在理解星系的形成及其与类星体活动的关系方面取得了许多重要成果，特别是，我们对z> 100的星系团进行了较系统的深近红外观测，1使用斯巴鲁望远镜以及APO 3.5 m和CFHT等一些外国设施，揭示了相对年轻星系的光度和聚集特性动态年轻集群的环境。为了研究射电星系3C 324中的原型高z星系团，我们在1999年发表了三篇论文，作为斯巴鲁望远镜的首批科学成果之一。2000年，我们利用斯巴鲁望远镜获得的新分析的光学数据扩大了研究。我们发现：（i）在hjgh红移星系团中广泛分布的颜色暗示了星系团中不同的恒星形成历史;（ii）光度和色分离暗示了星系的“有偏”形成。我们还发表了在B2 1336+28区域的暗红星系超团尺度成团的研究结果。在z=2.4的候选原星系团53 W 002区域，我们用Subaru获得了深近红外图像，发现（i）聚集在该区域的发射线星系在近红外波段很微弱，它们是低质量的年轻星暴星系;（ii）在这一区域内很少发现发育较好的静止星系，我们还对类星体宿主及其与星系形成的关系得到了一些有趣的结果。除了上面提到的对3C 324宿主的研究之外，（i）我们发表了一篇关于高z 2型类星体的论文，（ii）我们进行了ASCA调查的光学跟踪，（iii）我们正在进行Subaru/XMM Deep调查。
