On the population III binary black hole mergers with intermediate mass black holes: dependence on common envelope parameter
Kotaro Hijikawa, Tomoya Kinugawa, Ataru Tanikawa +2
The current gravitational wave (GW) detectors have successfully observed many binary compact objects, and the third generation ground-based GW detectors such as Einstein telescope…
Can Population III stars be major origins of both merging binary black holes and extremely metal poor stars?
Ataru Tanikawa, Gen Chiaki, Tomoya Kinugawa +2
Population (Pop) III stars, first stars, or metal-free stars are made of primordial gas. We have examined if they can be dominant origins of merging binary black holes (BHs) and ex…
On the population III binary black hole mergers beyond the pair-instability mass gap
Kotaro Hijikawa, Ataru Tanikawa, Tomoya Kinugawa +2
We perform a binary population synthesis calculation incorporating very massive population (Pop.) III stars up to 1500 , and investigate the nature of binary black hole (B…
Gravitational waves from Population III binary black holes are consistent with LIGO/Virgo O3a data for the chirp mass larger than
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
The probability number distribution function of binary black hole mergers observed by LIGO/Virgo O3a has double peaks as a function of chirp mass , total mass , primary b…
Impact of binary interactions on the diffuse supernova neutrino background
Shunsaku Horiuchi, Tomoya Kinugawa, Tomoya Takiwaki +2
Binary interactions, especially mass transfer and mergers, can strongly influence the evolution of massive stars and change their final properties and the occurrence of supernovae.…
Formation of Binary Black Holes Similar to GW190521 with a Total Mass of from Population III Binary Star Evolution
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
In the case of zero-metal (population III or Pop III) stars, we show that the total mass of binary black holes from binary Pop III star evolution can be , whi…
