Kinematics and Morphology of Large-Scale Nuclear Feeding in Active Galaxies

为了为类星体和其他遥远的活跃星系建立现实的理论模型，有必要了解负责补充产生释放能量的物质的机制。这项研究结合了光学和21厘米的数据，研究了附近活跃星系中中性氢的分布和运动，利用了这类天体良好的角度分辨率。扩展了首席研究员的早期工作，由此获得的定量运动学和形态学数据有助于阐明如此巨大的。规模 机制。

In order to develop realistic theoretical models for quasars and other distant active galaxies, an understanding of the mechanisms responsible for replenishing the material which generates the energy released is necessary. This research combines optical and 21 cm data on the distribution and motion of neutral hydrogen in nearby active galaxies, taking advantage of the good angular resolution available for such objects. Extending earlier work by the principal investigator, quantative kinematic and morphological data so obtained help elucidate such large.scale mechanisms.
