在凯克使用OSIRIS的NGC 4151的内部几角秒的PDKEEPAAA成像光谱学
NIR imaging spectroscopy of the inner few arcseconds of NGC 4151 with OSIRIS at Keck
摘要：
我们目前的H-和K-波段的数据从赛弗特1.5星系NGC 4151的内角秒获得的自适应光学辅助近红外成像场光谱仪OSIRIS在凯克天文台。我们提出的形态和动力学的大多数物种的检测，但集中在窄线区域的形态和动力学（跟踪的[Fe II] λ1.644μm的发射），从核喷射的等离子体（跟踪21厘米连续射电数据）和热H2气体之间的相互作用，并表征检测到的核HeI λ2.058 μm的吸收特性作为一个窄吸收线（NAL）现象。
英文摘要：
We present H- and K-band data from the inner arcsecond of the Seyfert 1.5 galaxy NGC 4151 obtained with the adaptive optics assisted near-infrared imaging field spectrograph OSIRIS at the Keck Observatory. We present the morphology and dynamics of most species detected but focus on the morphology and dynamics of the narrow line region (as traced by emission of [FeII] λ1.644μm), the interplay between plasma ejected from the nucleus (as traced by 21 cm continuum radio data) and hot H2 gas and characterize the detected nuclear HeI$λ2.058 μm absorption feature as a narrow absorption line (NAL) phenomenon.
