How to detect the shortest-period binary pulsars in the era of LISA
Koutarou Kyutoku, Yuki Nishino, Naoki Seto
We discuss a multimessenger strategy to detect radio pulses from Galactic binary neutron stars in a very tight orbit with the period shorter than 10 min. On one hand, all-sky surve…
Discrepancy in tidal deformability of GW170817 between the Advanced LIGO twin detectors
Tatsuya Narikawa, Nami Uchikata, Kyohei Kawaguchi +4
We find that the Hanford and Livingston detectors of Advanced LIGO derive a distinct posterior probability distribution of binary tidal deformability tilde{Lambda} of the first bin…
Effect of Inhomogeneity on Primordial Black Hole Formation in the Matter Dominated Era
Takafumi Kokubu, Koutarou Kyutoku, Kazunori Kohri +1
We investigate the effect of inhomogeneity on primordial black hole formation in the matter dominated era. In the gravitational collapse of an inhomogeneous density distribution, a…
Systematic effects from black hole-neutron star waveform model uncertainties on the neutron star equation of state
Kabir Chakravarti, Anuradha Gupta, Sukanta Bose +12
We identify various contributors of systematic effects in the measurement of the neutron star (NS) tidal deformability and quantify their magnitude for several types of neutron sta…
The origin of polarization in kilonovae and the case of the gravitational-wave counterpart AT 2017gfo
M. Bulla, S. Covino, K. Kyutoku +8
The Gravitational Wave (GW) event GW 170817 was generated by the coalescence of two neutron stars (NS) and produced an electromagnetic transient, labelled AT 2017gfo, that was targ…
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…
