标题： Pre-DEIMOS Pilot Surveys for DEEP

摘要： DEEP 是一个跨机构的合作项目，旨在利用凯克II 10米望远镜上的新仪器（DEIMOS）对超过10,000个场星系进行光谱巡天，直至视星等I ~ 23。其科学目标包括探索星系的形成与演化，绘制中高红移的大尺度结构图，以及限制暗物质的本质及其分布和宇宙学模型。DEEP 的独特之处在于获取了足够质量和分辨率的光谱，从而可以从较亮的星系子集中提取旋转曲线、速度弥散、年龄估计和化学丰度。在等待DEIMOS于1999年投入运行期间，DEEP 科学项目的第一个阶段主要集中于使用HST观测的领域进行LRIS观测。近期的亮点包括致密星系、高红移（z ~ 3）星系和遥远螺旋星系的红移和运动学研究。 显示英文摘要

摘要： DEEP is a multi-institutional program designed to undertake a major spectroscopic survey of 10,000+ field galaxies to I ~ 23 with a new instrument (DEIMOS) on the Keck II 10-m telescope. The scientific goals include exploring galaxy formation and evolution, mapping the large scale structure at moderate to high redshifts, and constraining the nature and distribution of dark matter and cosmology. DEEP is distinguished by securing spectra of sufficient quality and resolution to extract rotation curves, velocity dispersions, age estimates, and chemical abundances for a brighter subset of galaxies. While waiting for DEIMOS to be operational in 1999, the first phase of DEEP science programs has concentrated on LRIS observations of fields observed with HST. Recent highlights include redshift and kinematic studies of compact galaxies, high redshift (z ~ 3) galaxies, and distant spirals.
