Studies of Ionized Gas in Active Galaxies, Quasars, and Related Objects

本研究将继续利用CCD光谱仪和直接成像相机对星云、塞弗特星系、射电星系、其他活动星系核和类星体的发射线和连续光谱进行分光光度测量。CCD系统将通过各种发射在线和连续滤光片直接拍摄图像。这些测量，结合x射线、无线电、紫外线和红外数据，将用于分析所有类型活动星系核中电离气体的物理条件。关于电离、丰度、温度和密度的信息将在这项研究中得到强调。内部速度场和能量输入机制也将被研究。这些数据及其解释将增加我们对活动星系核的结构、性质、起源和演化的认识。首席研究员被认为是该研究领域的世界领导者。

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.
