Gaia 400,894 QSO constraint on the energy density of low-frequency gravitational waves
Shohei Aoyama, Daisuke Yamauchi, Maresuke Shiraishi +1
Low frequency gravitational waves (GWs) are keys to understanding cosmological inflation and super massive blackhole (SMBH) formation via blackhole mergers, while it is difficult t…
Galaxy simulation with the evolution of grain size distribution
Shohei Aoyama, Hiroyuki Hirashita, Kentaro Nagamine
We compute the evolution of interstellar dust in a hydrodynamic simulation of an isolated disc galaxy. We newly implement the evolution of full grain size distribution by sampling…
Dust scaling relations in a cosmological simulation
Kuan-Chou Hou, Shohei Aoyama, Hiroyuki Hirashita +2
To study the dust evolution in the cosmological structure formation history, we perform a smoothed particle hydrodynamic simulation with a dust enrichment model in a cosmological v…
Remodeling the evolution of grain size distribution in galaxies
Hiroyuki Hirashita, Shohei Aoyama
We revisit the evolution model of grain size distribution in a galaxy for the ultimate purpose of implementing it in hydrodynamical simulations. We simplify the previous model in s…
Comparison of cosmological simulations and deep submillimetre galaxy surveys
Shohei Aoyama, Hiroyuki Hirashita, Chen-Fatt Lim +8
Recent progress in submillimetre surveys by single-dish telescopes allows us to further challenge the consistency between cosmological simulations and observations. In particular,…
Cosmological simulation with dust formation and destruction
Shohei Aoyama, Kuan-Chou Hou, Hiroyuki Hirashita +2
To investigate the evolution of dust in a cosmological volume, we perform hydrodynamic simulations, in which the enrichment of metals and dust is treated self-consistently with sta…
