摘要

弥漫星际带(DIBs)自1922年以来就已为人所知，但它们的载体分子至今仍未被识别。我们简要介绍了DIB观测的历史，然后列出了任何提出的起源必须面对的约束条件，最后是使用哈勃太空望远镜上的宇宙起源光谱仪对紫外DIB的当前研究的预览。我们得出结论，多环芳烃符合所有列出的约束条件，但多环芳烃可能不是唯一负责dib的分子物种。

The Diffuse Interstellar Bands in History and in the UV

The diffuse interstellar bands (DIBs) have been known of since 1922, but their carrier molecules remain unidentified to this day. We present a brief history of DIB observations, followed by a list of constraints any suggested origin must face, and finally a preview of current research for ultraviolet DIBs using the Cosmic Origins Spectrograph on the Hubble Space Telescope . We conclude that PAHs are consistent with all the listed constraints, but that PAHs may not be the only molecular species responsible for the DIBs.
