Impact of radiative feedback on the initial mass function of metal-poor stars
Sunmyon Chon, Takashi Hosokawa, Kazuyuki Omukai +1
The stellar initial mass function (IMF) in the early universe is essential to understand the formation of ancient galaxies. To this end, we conduct a series of long-term radiation…
Exploring the nature of UV-bright galaxies detected by JWST: star formation, black hole accretion, or a non-universal IMF?
Alessandro Trinca, Raffaella Schneider, Rosa Valiante +4
We use the Cosmic Archaeology Tool (CAT) semi-analytical model to explore the contribution of Population (Pop) III/II stars and active galactic nuclei (AGNs) to the galaxy UV lumin…
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…
First emergence of cold accretion and supermassive star formation in the early universe
Masaki Kiyuna, Takashi Hosokawa, Sunmyon Chon
We investigate the first emergence of the so-called cold accretion, the accretion flows deeply penetrating a halo, in the early universe with cosmological N-body/SPH simulations. W…
