Mass Ratio of Binary Black Holes Determined from LIGO/Virgo Data Restricted to Small False Alarm Rate
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
We focus on gravitational-wave events of binary black-hole mergers up to the third observing run with the minimum false alarm rate smaller than . These even…
Stability of relativistic tidal response against small potential modification
Takuya Katagiri, Hiroyuki Nakano, Kazuyuki Omukai
The tidal response of compact objects in an inspiraling binary system is measured by a set of tidal Love and dissipation numbers imprinted in the gravitational waveforms. While a f…
Vanishing Love of Black Holes in General Relativity: From Spacetime Conformal Symmetry of a Two-dimensional Reduced Geometry
Takuya Katagiri, Masashi Kimura, Hiroyuki Nakano +1
We study the underlying structure of the vanishing of the Love numbers of both Schwarzschild and Kerr black holes in terms of spacetime conformal symmetry in a unified manner for t…
Eccentricity estimation from initial data for Numerical Relativity Simulations
Alessandro Ciarfella, James Healy, Carlos O. Lousto +1
We describe and study an instantaneous definition of eccentricity to be applied at the initial moment of full numerical simulations of binary black holes. The method consists of ev…
Constraints on Population I/II neutron star-black hole binary formation by gravitational wave and radio observations
Tomoya Kinugawa, Takashi Nakamura, Hiroyuki Nakano
Two neutron star (NS)-black hole (BH) binaries, GW200105 and GW200115 found in the LIGO/Virgo O3b run have smaller BH mass of 6--9\, which is consistent with Population…
Adiabatic waveforms from extreme-mass-ratio inspirals: an analytical approach
Soichiro Isoyama, Ryuichi Fujita, Alvin J. K. Chua +3
Scientific analysis for the gravitational-wave detector LISA will require theoretical waveforms from extreme-mass-ratio inspirals (EMRIs) that extensively cover all possible orbita…
