Morphology and Evolution of the Interstellar Medium in Disk Galaxies

在这项拨款中进行的研究将集中在对附近盘状星系中星际介质(ISM)的观测。这项研究将解决我们对星际介质理解中的几个悬而未决的问题。它将讨论中性和电离氢气的形态，以及对哈勃类型和恒星形成速度的依赖。它将研究弥散的电离气体在星际介质中的作用，并将研究位于银河系平面上方、远离其中心的电离气体区域(HII区域)。

The research to be carried out in this grant will focus on observations of the interstellar medium (ISM) in nearby disk galaxies. The research will address several unresolved issues in our understanding of the interstellar medium. It will address the morphology of the neutral and ionized hydrogen gas and the dependence on Hubble type and star formation rates. It will examine the role of diffuse ionized gas in the interstellar medium and will study ionized gas regions (HII regions) that are located high above the plane of the galaxy and far from its center.
