Active Galactic Nuclei, Quasars and Primeval Galaxies

9321441安东努奇这项研究将涉及对活动星系核、类星体和原始星系的性质的研究。一种新的光谱偏振技术将被用来获得活动核的多方向图像，并利用这些结果与在其他波长的某些观测相结合。将会有对无线电静默类星体的研究。将使用光学宽带和近红外窄带成像来测试某些特别选定的、在深光学CCD图像上无法识别的非常微弱的射电源是否可能处于超高红移(6{符号163\f“符号”}Z{符号163\f“符号”}20)。***

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). ***
