Radial properties of dust in galaxies: Comparison between observations and isolated galaxy simulations
S. A. van der Giessen, K. Matsumoto, M. Relano +8
We study the importance of several processes that influence the evolution of dust and its grain size distribution on spatially resolved scales in nearby galaxies. Here, we compiled…
Evolution of grain size distribution in the circum-galactic medium
Hiroyuki Hirashita
In order to theoretically understand dust properties in the circum-galactic medium (CGM), we construct a dust evolution model that incorporates the evolution of grain size distribu…
Dust enrichment in the circum-galactic medium
Mau Otsuki, Hiroyuki Hirashita
To understand the origin of dust in the circum-galactic medium (CGM), we develop a dust enrichment model. We describe each of the central galaxy and its CGM as a single zone, and c…
Observational signatures of the dust size evolution in isolated galaxy simulations
Kosei Matsumoto, Hiroyuki Hirashita, Kentaro Nagamine +9
We aim to provide observational signatures of the dust size evolution in the ISM. In particular, we explore indicators of the polycyclic aromatic hydrocarbon (PAH) mass fraction ($…
Submillimetre galaxies as laboratories for dust grain coagulation
Hiroyuki Hirashita, Chian-Chou Chen
Coagulation in the dense interstellar medium (ISM) is an important process that determines the size of the largest grains. We use submillimetre galaxies (SMGs) as laboratories of g…
Effects of dust grain size distribution on the abundances of CO and H in galaxy evolution
Hiroyuki Hirashita
We model the effect of grain size distribution in a galaxy on the evolution of CO and H abundances. The formation and dissociation of CO and H in typical dense clouds are m…
