Probing the Limits of Nuclear Activity in COSMOS

这项研究计划将利用宇宙场上的多波长数据来选择具有广泛光学和红外性质的活动星系核(AGN)。麦哲伦/iMACs多目标光谱将用于光谱确认约3000个活动星系核，在红移3到达经典的Seyfert/类星体边界，其中包括约300个红移为3的类星体。深度多波长观测将允许研究宇宙中活动星系核的总能量密度，包括遮挡活动星系核到红移~1和类型1活动星系核到红移~4的测辐射光度函数。时间域数据将用于测量连续体和谱线之间的混响。

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.
