Discrimination of Pop III Stars by Detection of GWs from Binary Black Hole Coalescences |
|
Abstract |
We will display to confirm the existence of Population III (Pop III) stars by the detection of gravitational waves (GWs) from binary black hole coalescences. Since the Pop III star tend to be massive, the major part the Pop III binary becomes black hole binary. We perform the simulation of GW detection for Population I (Pop I), Population II (Pop II) and Pop III black hole binaries. We employ a likelihood to compare the mass distribution of GW detections and evaluate its performance to discriminate Pop I, II, and III models. The results strongly suggest that the GW detection will demonstrate the existence of Pop III. |
