Pre-DECIGO can get the smoking gun to decide the astrophysical or cosmological origin of GW150914-like binary black holes
Takashi Nakamura, Masaki Ando, Tomoya Kinugawa +9
Pre-DECIGO consists of three spacecraft arranged in an equilateral triangle with 100km arm lengths orbiting 2000km above the surface of the earth. It is hoped that the launch date…
Estimate of the radius responsible for quasinormal modes in the extreme Kerr limit and asymptotic behavior of the Sasaki-Nakamura transformation
Hiroyuki Nakano, Norichika Sago, Takahiro Tanaka +1
The Sasaki-Nakamura transformation gives a short-ranged potential and a convergent source term for the master equation of perturbations in the Kerr space-time. In this paper, we st…
The detection of Quasinormal Mode of Pop III Binary Black Hole merger with final and would confirm the strong gravity space-time around which is only times the event horizon radius
Takashi Nakamura, Hiroyuki Nakano, Takahiro Tanaka
Recent population synthesis simulations of Pop III stars suggest that the event rate of coalescence of -- binary black holes can be high enough for the d…
