This research will continue spectrophotometric measurements with the Charge-Coupled Device (CCD) spectrograph and direct imaging camera of the emission line and continuous spectra of nebulae, Seyfert galaxies, radio galaxies, other active galactic nuclei, and quasars. Direct images will be taken with the CCD system through various emission-line and continuum filters. These measurements, in conjunction with X-ray, radio, ultraviolet and infrared data will be used to analyze the physical conditions in the ionized gas in all types of active galactic nuclei. Information on ionization, abundances, temperatures and densities will be emphasized in this research. The internal velocity fields and energy-input mechanisms will also be investigated. These data, and their interpretation, will add to our knowledge of the structure, nature, origin, and evolution of active galactic nuclei. The Principal Investigator is regarded as a world leader in this field of research.

这项研究将继续分光光度测量， CCD摄谱仪与直接成像 星云发射线和连续光谱的照相机， 塞弗特星系，射电星系，其他活动星系核， 类星体 直接图像将通过CCD系统拍摄， 各种发射线和连续滤光片。 这些测量， 结合X射线、无线电、紫外线和红外线数据 将用于分析电离气体中的物理条件 所有类型的活动星系核。 关于电离的信息， 本文将强调丰度、温度和密度 research. 内部速度场和能量输入机制 也将被调查。 这些数据及其解释 将增加我们对结构、性质、起源和 活动星系核的演化 首席研究员被认为是这方面的世界领导者。 研究领域。
