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…
Formation of mass gap compact object and black hole binary from Population III stars
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
We performed population synthesis simulations of Population III binary stars with Maxwellian kick velocity distribution when MGCOs (Mass Gap Compact Objects with mass 2--5$\,M_{\od…
Spectral Puzzle of the Off-Axis Gamma-Ray Burst in GW170817
Kunihito Ioka, Takashi Nakamura
Gravitational waves from a merger of two neutron stars (NSs) were discovered for the first time in GW170817, together with diverse electromagnetic counterparts, providing a direct…
The possible existence of Pop III NS-BH binary and its detectability
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
In the population synthesis simulations of Pop III stars, many BH (Black Hole)-BH binaries with merger time less than the age of the Universe are formed, while NS (Ne…
Gravitational wave quasinormal mode from Population III massive black hole binaries in various models of population synthesis
Tomoya Kinugawa, Hiroyuki Nakano, Takashi Nakamura
Focusing on the remnant black holes after merging binary black holes, we show that ringdown gravitational waves of Population III binary black holes mergers can be detected with th…
The detection of quasinormal mode with would prove a sphere soaking in the ergoregion of the Kerr space-time
Hiroyuki Nakano, Takashi Nakamura, Takahiro Tanaka
Recent numerical relativity simulations of mergers of binary black holes suggest that the maximum final value of is for the coalescence of two equal mass black ho…
