Radiative properties of the first galaxies: rapid transition between blue and red
Shohei Arata, Hidenobu Yajima, Kentaro Nagamine +2
Recent observations have successfully detected UV-bright and infrared-bright galaxies in the epoch of reionization. However, the origin of their radiative properties has not been u…
Probing the High-Redshift Universe with SPICA: Toward the Epoch of Reionization and Beyond
E. Egami, S. Gallerani, R. Schneider +36
With the recent discovery of a dozen dusty star-forming galaxies and around 30 quasars at z>5 that are hyper-luminous in the infrared ( L, where $μ…
Stellar mass dependence of the 21-cm signal around the first star and its impact on the global signal
Toshiyuki Tanaka, Kenji Hasegawa, Hidenobu Yajima +2
The 21-cm signal in the vicinity of the first stars is expected to reflect properties of the first stars. In this study we pay special attention to tracing the time evolution of th…
Condition for dust evacuation from the first galaxies
Hajime Fukushima, Hidenobu Yajima, Kazuyuki Omukai
Dust enables low-mass stars to form from low-metallicity gas by inducing fragmentation of clouds via the cooling by its thermal emission. Dust may, however, be evacuated from star-…
Stunted accretion growth of black holes by combined effect of the flow angular momentum and radiation feedback
Kazuyuki Sugimura, Takashi Hosokawa, Hidenobu Yajima +2
Accretion on to seed black holes (BHs) is believed to play a crucial role in formation of supermassive BHs observed at high-redshift (z>6). Here, we investigate the combined effect…
Suppression of globular cluster formation in metal-poor gas clouds by Lyman-alpha radiation feedback
Makito Abe, Hidenobu Yajima
We study the impact of Ly radiation feedback on globular cluster (GC) formation. In this Letter, we analytically derive the relation between star formation efficiency (SFE) and…
SEURAT: SPH scheme extended with ultraviolet line radiative transfer
Makito Abe, Hiroyuki Suzuki, Kenji Hasegawa +3
We present a novel Lyman alpha (Ly) radiative transfer code, SEURAT, where line scatterings are solved adaptively with the resolution of the smoothed particle hydrodynamics (SPH…
SILVERRUSH. VI. A simulation of Ly emitters in the reionization epoch and a comparison with Subaru Hyper Suprime-Cam survey early data
Akio K. Inoue, Kenji Hasegawa, Tomoaki Ishiyama +12
The survey of Lyman emitters (LAEs) with Subaru Hyper Suprime-Cam, called SILVERRUSH (Ouchi et al.), is producing massive data of LAEs at . Here we present LAE simul…
