For the present study, I used the data of the infrared astronomical satellite, AKARI, which were taken in the obervational programs, "the interstellar medium in our Galaxy and nearby galaxies," and "all-sky surveys". Improving the method to process AKARI far-infrared imaging data, I have elucidated the evolution of dust grains in various interstellar environments of nearby galaxies. Because AKARI covered all the sky with improved sensitivities, I derived information on properties of dust in various harsh environments, providing entirely new knowledge on the shattering and destruction of dust, and processing of polycyclic aromatic hydrocarbons (PAHs). In particular, I find that copious amounts of dust are flowing out of galaxies by galactic superwinds, enriching the intergalactic space with dust. I also reveal the presence of PAHs in elliptical galaxies with unusual spectral features, demonstrating importance of the material processing in the interstellar space.

在本研究中，我使用了红外天文卫星AKARI的数据，这些数据是在观测计划中拍摄的，“我们银河系和附近星系的星际介质”和“全天巡天”。改进了AKARI远红外成像数据的处理方法，阐明了尘埃颗粒在邻近星系各种星际环境中的演化。由于AKARI以更高的灵敏度覆盖了整个天空，我获得了各种恶劣环境下灰尘特性的信息，提供了关于灰尘粉碎和破坏以及多环芳烃（PAH）处理的全新知识。特别是，我发现大量的尘埃正通过星系超级风流出星系，用尘埃丰富了星系际空间。我还揭示了椭圆星系中存在的多环芳烃与不寻常的光谱特征，展示了星际空间中的材料处理的重要性。
