ABSTRACT 9321441 Antonucci This research will involve studies of the nature of active galactic nuclei, quasars, and primeval galaxies. A new technique of spectropolarimetry will be used to obtain multidirectional views of active nuclei, and to capitalize on the results with certain observations at other wavelengths. There will be studies of radio-quiet quasars. Optical broadband and near-IR narrow-and broadband imaging will be used to test whether certain specially-selected very faint radio sources, unidentified on deep optical CCD images, could be at ultra-high redshifts (6{SYMBOL 163 \f "Symbol"} Z {SYMBOL 163 \f "Symbol"} 20). ***

这项研究将涉及对活动星系核、类星体和原始星系性质的研究。一种新的光谱偏振法技术将用于获得活动原子核的多向视图，并利用在其他波长的某些观测结果。将会有对无线电无噪声类星体的研究。光学宽带和近红外窄带和宽带成像将用于测试某些特别选择的非常微弱的射电源，在深层光学CCD图像上无法识别，是否可以处于超高红移（6{SYMBOL 163 \f“SYMBOL”}Z {SYMBOL 163 \f“SYMBOL”}20）。＊＊＊
