Direct-collapse black hole formation induced by internal radiation of host halos
Gen Chiaki, Sunmyon Chon, Kazuyuki Omukai +3
We estimate the fraction of halos that host supermassive black holes (SMBHs) forming through the direct collapse (DC) scenario by using cosmological N -body simulations combined wi…

Supernova dust formation and the grain growth in the early universe: The critical metallicity for low-mass star formation
Gen Chiaki, Stefania Marassi, Takaya Nozawa +5
We investigate the condition for the formation of low-mass second-generation stars in the early universe. It has been proposed that gas cooling by dust thermal emission can trigger…

Low-mass star formation triggered by early supernova explosions
Gen Chiaki, Naoki Yoshida, Tetsu Kitayama
We study the formation of low-mass and extremely metal-poor stars in the early universe. Our study is motivated by the recent discovery of a low-mass (M < 0.8 Msun) and extremely m…
