Forecasting Tidal Disruption Events by Binary Black Hole Roulettes
Naoki Seto, Koutarou Kyutoku
We discuss the gravitational wave emission and the orbital evolution of a hierarchical triple system composed of an inner binary black hole (BBH) and an outer tertiary. Depending o…
Gravitational-wave cosmography with LISA and the Hubble tension
Koutarou Kyutoku, Naoki Seto
We propose that stellar-mass binary black holes like GW150914 will become a tool to explore the local Universe within ~100Mpc in the era of the Laser Interferometer Space Antenna (…
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…
Concise estimate of the expected number of detections for stellar-mass binary black holes by eLISA
Koutarou Kyutoku, Naoki Seto
We study prospects for detecting extragalactic binary black holes similar to GW150914 by evolved Laser Interferometer Space Antenna (eLISA). We find that the majority of detected b…
Prospects of eLISA for Detecting Galactic Binary Black Holes Similar to GW150914
Naoki Seto
We discuss the prospects of eLISA for detecting gravitational waves (GWs) from Galactic binary black holes (BBHs) similar to GW150914. For a comoving merger rate that is consistent…
