与AKARI一起，我们对星系各种环境中的星际尘埃颗粒进行了系统的研究。在许多情况下，尘埃的红外辐射是追踪星系中恒星形成活动的重要工具。然而，它不仅仅是恒星形成的示踪剂。AKARI还揭示了与星星形成无关的区域中尘埃颗粒的详细性质，其中一些发现与我们以前的经验知识不符。由于其独特的能力，如近红外和远红外光谱，以及全天空覆盖，AKARI提供了新的知识，包括多环芳烃的碳质颗粒的加工。我们目前的最新结果，从我们的AKARI观测ISM在我们的银河系和附近的星系。
With AKARI, we have performed a systematic study of interstellar dust grains in various environments of galaxies. In many cases, the IR emission of dust is an important tool to trace star-forming activities in galaxies. However it is much more than just star-formation tracers. AKARI has revealed the detailed properties of dust grains in regions not relevant to star formation as well, some of which are found not to follow our old empirical knowledge. Because of its unique capabilities, such as near- and far-IR spectroscopy, and all-sky coverage, AKARI has provided new knowledge on the processing of carbonaceous grains including polycyclic aromatic hydrocarbons. We present the latest results obtained from our AKARI observations of the ISM in our Galaxy and nearby galaxies.
