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.

在这项资助下进行的研究将集中在 对邻近盘中星际介质的观测 星系 这项研究将解决几个悬而未决的问题， 我们对星际介质的理解 它将解决 中性和离子化氢气的形态和 依赖于哈勃类型和星星形成率。 它将 研究星际介质中弥漫电离气体的作用 并将研究电离气体区域（HII区域）， 在银河系平面之上，远离中心。
