Gravitational Wave Physics and Astronomy in the nascent era
Makoto Arimoto, Hideki Asada, Michael L. Cherry +50
The detections of gravitational waves (GW) by LIGO/Virgo collaborations provide various possibilities to physics and astronomy. We are quite sure that GW observations will develop…
Reducing orbital eccentricity in initial data of black hole--neutron star binaries in the puncture framework
Koutarou Kyutoku, Kyohei Kawaguchi, Kenta Kiuchi +2
We develop a method to compute low-eccentricity initial data of black hole--neutron star binaries in the puncture framework extending previous work on other types of compact binari…
Overview of KAGRA : KAGRA science
KAGRA Collaboration, T. Akutsu, M. Ando +240
KAGRA is a newly build gravitational-wave observatory, a laser interferometer with 3 km arm length, located in Kamioka, Gifu, Japan. In this paper in the series of KAGRA-featured a…
Reanalysis of the binary neutron star mergers GW170817 and GW190425 using numerical-relativity calibrated waveform models
Tatsuya Narikawa, Nami Uchikata, Kyohei Kawaguchi +4
We reanalyze gravitational waves from binary-neutron-star mergers GW170817 and GW190425 using a numerical-relativity (NR) calibrated waveform model, the TF2+_Kyoto model, which inc…
Frequency-domain gravitational waveform models for inspiraling binary neutron stars
Kyohei Kawaguchi, Kenta Kiuchi, Koutarou Kyutoku +3
We develop a model for frequency-domain gravitational waveforms from inspiraling binary neutron stars. Our waveform model is calibrated by comparison with hybrid waveforms construc…
Extracting the orbital axis from gravitational waves of precessing binary systems
Kyohei Kawaguchi, Koutarou Kyutoku, Hiroyuki Nakano +1
We present a new method for extracting the instantaneous orbital axis only from gravitational wave strains of precessing binary systems observed from a particular observer directio…
