Force convergence in Monte Carlo Lyman-alpha radiative transfer
Joshua Kasiri, Aaron Smith, Kevin Lorinc +2
Monte Carlo radiative transfer (MCRT) is widely used to model Lyman-alpha (Lya) resonant-line transport, but convergence is difficult to assess in optically thick media where photo…
Blue-tilted spectral running and the JWST early galaxy tension
Mikage U. Kobayashi, Gen Chiaki, Kazutaka Kimura +4
Recently, the James Webb Space Telescope (JWST) collaboration has found the unexpectedly large abundance of massive galaxies with stellar masses of at high…
An Explicit M1 Radiation-hydrodynamics Scheme for 3D Protostellar Evolution
Kazutaka Kimura, Kazuyuki Sugimura, Takashi Hosokawa +2
We present a radiation-hydrodynamics (RHD) scheme that enables 3D simulations resolving both protostellar interiors and their surrounding accretion flows within a single framework,…
Massive Black Hole Seed Formation in Strong X-ray Environments at High Redshift
Kazutaka Kimura, Kohei Inayoshi, Kazuyuki Omukai
Direct collapse of pristine gas in early galaxies is a promissing pathway for forming supermassive black holes (BHs) powering active galactic nuclei (AGNs) at the epoch of reioniza…
3D Radiation-Hydrodynamic Simulations Resolving Interior of Rapidly Accreting Primordial Protostar
Kazutaka Kimura, Takashi Hosokawa, Kazuyuki Sugimura +1
Direct collapse of supermassive stars is a possible pathway to form supermassive black hole seeds at high redshifts. Whereas previous three-dimensional (3D) simulations demonstrate…
Growth of Massive Disk and Early Disk Fragmentation in the Primordial Star Formation
Kazutaka Kimura, Takashi Hosokawa, Kazuyuki Sugimura
Recent high-resolution simulations demonstrate that disks around primordial protostars easily fragment in the accretion phase before the protostars accrete less than a solar mass.…
