论文摘要
到目前为止，矮星系是宇宙中众多星系，显示出与更大和更发光的表亲的特性。这篇综述着重于已知矮小的矮人的星际介质的物理和化学特性。将讨论中性和电离气体成分以及灰尘的影响，以及这些来源中活性核存在的第一指示。考虑到早期宇宙中原始绿色星系的原始氦气丰度与年轻的，有时是原始的 - 半河流来源的相似性，还解决了宇宙学的含义。
Dwarf galaxies are by far the most numerous galaxies in the Universe, showing properties that are quite different from those of their larger and more luminous cousins. This review focuses on the physical and chemical properties of the interstellar medium of those dwarfs that are known to host significant amounts of gas and dust. The neutral and ionized gas components and the impact of the dust will be discussed, as well as first indications for the existence of active nuclei in these sources. Cosmological implications are also addressed, considering the primordial helium abundance and the similarity of local Green Pea galaxies with young, sometimes proto-galactic sources in the early Universe.
