论文摘要
我们研究了附近星系中连续光晕的高度倾斜星系的垂直分布 - EVLA调查（Chang -es）。我们通过量化系统的扩展效应，从而得出直接测量的校正方程，从而探索了从相对边缘星系的矩-0图像中得出HI磁盘尺度高度的可行性。来自Chang-s样品相对边缘星系的校正的HI磁盘尺度高度显示了与气盘垂直结构的准平衡模型一致的趋势。该过程提供了一种方便的方法来推导规模高度，并且将来可以轻松地应用于统计样本。
We study the vertical distribution of the highly inclined galaxies from the Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES). We explore the feasibility of photometrically deriving the HI disk scale-heights from the moment-0 images of the relatively edge-on galaxies with inclination >80 deg, by quantifying the systematic broadening effects and thus deriving correction equations for direct measurements. The corrected HI disk scale-heights of the relatively edge-on galaxies from the CHANG-ES sample show trends consistent with the quasi-equilibrium model of the vertical structure of gas disks. The procedure provide a convenient way to derive the scale-heights and can easily be applied to statistical samples in the future.
