Galactic and Extragalactic Research with Schmidt Telescopes

这笔赠款支持Peter Pesch博士和Nicholas Sanduleak博士基于凯斯西部储备大学位于亚利桑那州基特峰的Burrell Schmidt望远镜和位于Cerro Tolo美洲天文台的Curtis Schmidt望远镜进行的观测所做的研究。目前正在进行的主要调查是非常富有成效的搜索暗蓝色和/或发射线星系、有或没有发射特征的准恒星物体、可能的蓝星、主序晚B和A星、A和F、F和G亚矮星、以及暗碳和晚M型恒星。计划在Burrell Schmidt上使用电荷耦合装置进行探索性观测，以确定哪些直接和光谱观测项目值得进行。对银河系结构和河外天体分布的研究需要进行调查，以确定将被详细研究的天体。对大片天空的观测对于研究银河系中的人口分布特别重要，以确定朝向核、晕和反中心的不同特征。这些研究人员在凯斯韦斯特进行的调查是进行详细后续调查的关键第一步。

This grant supports research by Drs. Peter Pesch and Nicholas Sanduleak based on observations made with Case Western Reserve University's Burrell Schmidt telescope, located on Kitt Peak in Arizona, and with the Curtis Schmidt, located at Cerro Tololo Inter-American Observatory. The principal survey now being carried out is a very fruitful search for faint blue and/or emission line galaxies, quasi-stellar objects with and without emission features, probable blue stars, main-sequence late B and A stars, Population II stars of types A and F, F and G subdwarfs, and faint carbon and late M type stars. Exploratory observations with a charge coupled device on the Burrell Schmidt are planned to determine what direct and spectroscopic observational programs would be worthwhile to undertake. Investigations of galactic structure and the distribution of extragalactic objects require surveys to identify the objects which will be studied in detail. Surveys over large parts of the sky are especially important for studies of the population distribution in our galaxy to determine the different characteristics towards the nucleus, halo and anticenter. The surveys conducted by these researchers at Case Western are a vital first step to detailed follow-on investigations.
