Spin misalignment of black hole binaries from young star clusters: implications for the origin of gravitational waves events
Alessandro Alberto Trani, Ataru Tanikawa, Michiko S. Fujii +2
Recent studies indicate that the progenitors of merging black hole (BH) binaries from young star clusters can undergo a common envelope phase just like isolated binaries. If the st…
Spin distribution of binary black holes formed in open clusters
Jun Kumamoto, Michiko S. Fujii, Alessandro A. Trani +1
We performed direct N-body simulations of open clusters with four different metallicities. To investigate the effective spins of merging binary black holes (BBHs) originated from t…
Impact of initial mass functions on the dynamical channel of gravitational wave sources
Long Wang, Michiko S. Fujii, Ataru Tanikawa
Dynamically formed black hole (BH) binaries (BBHs) are important sources of gravitational waves (GWs). Globular clusters (GCs) provide a major environment to produce such BBHs, but…
Gaia's Detectability of Black Hole-Main Sequence Star Binaries Formed in Open Clusters
Minori Shikauchi, Jun Kumamoto, Ataru Tanikawa +1
Black hole-main sequence star (BH-MS) binaries are one of the targets of the future data releases of the astrometric satellite {\it Gaia}. They are supposed to be formed in two mai…
Merger rate density of binary black holes formed in open clusters
Jun Kumamoto, Michiko S. Fujii, Ataru Tanikawa
Several binary black holes (BBHs) have been observed using gravitational wave detectors. For the formation mechanism of BBHs, two main mechanisms, isolated binary evolution and dyn…
Formation rate of LB-1-like systems through dynamical interactions
Ataru Tanikawa, Tomoya Kinugawa, Jun Kumamoto +1
We estimate formation rates of LB-1-like systems through dynamical interactions in the framework of the theory of stellar evolution before the discovery of the LB-1 system. The LB-…
Gravitational-Wave Emission from Binary Black Holes Formed in Open Clusters
Jun Kumamoto, Michiko S. Fujii, Ataru Tanikawa
In order to investigate the formation rate of binary black holes (BBHs) in stellar clusters with a mass comparable to open clusters, we performed a series of direct -body simula…
The Detection Rates of Merging Binary Black Holes Originating from Star Clusters and Their Mass Function
Michiko Fujii, Ataru Tanikawa, Junichiro Makino
Advanced LIGO achieved the first detection of the gravitational wave, which was from a merging binary black hole (BBH). In the near future, more merger events will be observed, and…
