Amplification and saturation of turbulent magnetic field in collapsing primordial gas clouds

Sho Higashi, Hajime Susa, Christoph Federrath +1

Recent numerical studies suggest that magnetic fields play an important role in primordial star formation in the early universe. However, the detailed evolution of the magnetic fie…

Merger Conditions of Population III Protostar Binaries

Takanobu Kirihara, Hajime Susa, Takashi Hosokawa +1

Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries i…

Saturation level of turbulence in collapsing gas clouds

Sho Higashi, Hajime Susa, Gen Chiaki

We investigate the physical mechanism that decides the saturation level of turbulence in collapsing gas clouds. We perform a suite of high-resolution numerical simulations followin…

Merger rate density of binary black holes through isolated Population I, II, III and extremely metal-poor binary star evolution

Ataru Tanikawa, Takashi Yoshida, Tomoya Kinugawa +4

We investigate the formation of merging binary black holes (BHs) through isolated binary evolution, performing binary population synthesis calculations covering an unprecedentedly…

Amplification of turbulence in contracting prestellar cores in primordial minihalos

Sho Higashi, Hajime Susa, Gen Chiaki

We investigate the amplification of turbulence through gravitational contraction of the primordial gas in minihalos. We perform numerical simulations to follow the cloud collapse,…

Gravitational Wave Physics and Astronomy in the nascent era

Makoto Arimoto, Hideki Asada, Michael L. Cherry +50

The detections of gravitational waves (GW) by LIGO/Virgo collaborations provide various possibilities to physics and astronomy. We are quite sure that GW observations will develop…
