This research program will use the multiwavelength data on the COSMOS field to select Active Galactic Nuclei (AGNs) with a wide range of optical and IR properties. Multi-object spectroscopy with Magellan/IMACS will be used to spectroscopically confirm ~3000 AGNs, reaching the classical Seyfert/quasar boundary at a redshift of 3 and including about 300 quasars with redshift 3. The deep multiwavelength observations will allow studies of the total AGN energy density in the universe, including a bolometric luminosity function for obscured AGN to redshift ~1 and Type 1 AGN to redshfit ~4. Time domain data will be used to measure reverberation between the continuum and the lines.

这项研究计划将使用COSMOS领域的多波长数据来选择具有广泛光学和红外特性的活动星系核。Magellan/IMACS的多目标光谱学将用于光谱学确认约3000个活动星系核，达到红移为3的经典Seyfert/类星体边界，包括约300个红移为3的类星体。深多波长观测将允许研究活动星系核在宇宙中的总能量密度，包括暗活动星系核红移~1和1型活动星系核红移~4的热光度函数。 时域数据将用于测量连续体和线路之间的混响。
