Abstract BERSHADY, M. A. AST-9618849 Funds will be used to design, build and install two- dimensional fiber-optical arrays into the 9m Hobby-Eberly Telescope's Medium Resolution Spectrograph. Two arrays will be built to optimize integral-field spectroscopy for kinematic studies of individual nearby and moderately distant galaxies. One array spans over 30 arcsec using 1 arcsec fibers to densely sample slits at 4 position angles (R 10,900). The second array spans 15 arcsec using 0.5 arcsec fibers to densely sample a core area of ~60 square arcsecs (R 21,800).

BERSHADY, m.a. AST-9618849基金将用于设计、建造和安装9米霍比-埃伯利望远镜中分辨率光谱仪的二维光纤阵列。将建立两个阵列来优化积分场光谱，用于单个近星系和中等距离星系的运动学研究。一个阵列跨度超过30弧秒，使用1弧秒光纤在4个位置角度（r10,900）密集取样狭缝。第二个阵列跨度为15弧秒，使用0.5弧秒的光纤密集采样约60平方弧秒（R 21800）的核心区域。
