Gravitational waves from Population III binary black holes are consistent with LIGO/Virgo O3a data for the chirp mass larger than
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
The probability number distribution function of binary black hole mergers observed by LIGO/Virgo O3a has double peaks as a function of chirp mass , total mass , primary b…
Chirp Mass and Spin of Binary Black Holes from First Star Remnants
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
We performed Population III (Pop III) binary evolution by using population synthesis simulations for seven different models. We found that Pop III binaries tend to be binary black…
How Robust is the N = 34 Subshell Closure? First Spectroscopy of Ar
H. N. Liu, A. Obertelli, P. Doornenbal +77
The first -ray spectroscopy of Ar, with the neutron number N = 34, was measured using the K(p,2p) one-proton removal reaction at 210 MeV/u at the RIBF facili…
Multiband Gravitational-Wave Astronomy: Observing binary inspirals with a decihertz detector, B-DECIGO
Soichiro Isoyama, Hiroyuki Nakano, Takashi Nakamura
An evolving Japanese gravitational-wave (GW) mission in the deci-Hz band: B-DECIGO (DECihertz laser Interferometer Gravitational wave Observatory) will enable us to detect GW150914…
How to confirm the existence of population III stars by observations of gravitational waves
Akinobu Miyamoto, Tomoya Kinugawa, Takashi Nakamura +1
We propose a method for confirmation of the existence of Population III (Pop III) stars with massive black hole binaries as GW150914 in gravitational wave (GW) observation. When we…
Intrisic Dispersion of Correlations among Ep, Lp, and Eiso of Gamma Ray Bursts depends on the quality of Data Set
Ryo Tsutsui, Takashi Nakamura, Daisuke Yonetoku +2
We reconsider correlations among the spectral peak energy (), 1-second peak luminosity () and isotropic energy (\Eiso), using the database constructed by \citet{yonetoku1…
