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…
Search for a stochastic gravitational wave background at 1-5 Hz with Torsion-bar Antenna
Yuya Kuwahara, Ayaka Shoda, Kazunari Eda +1
We set the first upper limit on the stochastic gravitational wave (GW) background in the frequency range of using a Torsion-bar Antenna (TOBA). A TOBA is a GW de…
Gravitational waves as a probe of dark matter mini-spikes
Kazunari Eda, Yousuke Itoh, Sachiko Kuroyanagi +1
Recent studies show that an intermediate mass black hole (IMBH) may develop a dark matter (DM) mini-halo according to some BH formation scenarios. We consider a binary system compo…
Improving parameter estimation accuracy with torsion-bar antennas
Kazunari Eda, Ayaka Shoda, Yousuke Itoh +1
We propose a new antenna configuration of a torsion-bar antenna (TOBA) and study its performance. A TOBA is a novel type of an antenna for low-frequency gravitational waves (GWs) w…
