Research activity in astronomy and astrophysics at Columbia University has recently undergone a major expansion with the allocation of substantial new resources to the Departments of Physics and Astronomy: Nine new faculty members have been hired during the past five years, over $2 million has been spent or committed for building renovation and another $0.4 M has been awarded in startup money for the new faculty. In addition, the University has agreed to allot $320,000 in 2:1 matching funds toward the purchase and installation of a modern computing facility to support the varied research programs of its young faculty. This award provides the remaining 1/3 of the funds required to complete the acquisition of this system. Major science projects which necessitate the CONVEX-based facility are already underway; these include a complete volume-limited HI survey fo the Hydra cluster of galaxies and a number of other large aperture synthesis spectral line projects conducted by the PI, a survey of the Galactic plane at 327 MHz which exceeds all previous surveys be a factor of more than 30 in both resolution and sensitivity, analysis of several hundred echelle spectra of K giants and extensive crowded-field photometry in the Galactic bulge as part of a larger program directed at unravelling the chemical and dynamical evolution of the Galaxy, analysis of other extensive data sets including high-resolution optical spectra of white dwarfs, emission line regions of active galactic nuclei, and quasar absorption line systems, and several theoretical projects related to time-dependent convection in stars, numerical studies in the formation and evolution of galaxies, and the investigation of a novel approach to thermal instabilities in the interstellar medium. The research computing facility is essential for the conduct of much of this research program.

哥伦比亚大学的天文学和天体物理学研究活动 大学最近经历了一个重大的扩张与 向各部分配大量新资源， 物理学和天文学：聘请了9名新教师 在过去的五年里，已经花费了200多万美元， 已承诺用于建筑物翻新，另外40万美元已 新教员的启动资金 此外该 大学已同意以2：1的比例分配32万美元的配套资金 购买和安装一个现代化的计算设备 以支持其年轻教师的各种研究项目。 这 奖励提供完成所需资金的其余1/3 这套系统的收购。 重大科学项目， 需要CONVEX的设施已经在进行中;这些 包括对Hydra星团进行一次完整的体积有限的HI调查 星系和其他一些大口径合成光谱 PI进行的一系列项目，对银河系平面的调查 在327兆赫，这超过了所有以前的调查是一个因素， 在分辨率和灵敏度方面均超过30， K巨星中阶梯光谱和广布的拥挤场 作为更大计划的一部分， 旨在解开分子的化学和动力学演变 银河，分析其他广泛的数据集，包括 白色矮星发射线高分辨光谱 活动星系核区和类星体吸收线 系统，以及与时间相关的几个理论项目 恒星中的对流，形成和 星系的演化，以及对一种新方法的研究 星际介质中的热不稳定性。 研究 计算设施是进行大部分这类活动所必需的 研究计划。
