Probing Gravitational Parity Violation with Gravitational Waves from Stellar-mass Black Hole Binaries
Kent Yagi, Huan Yang
The recent discovery of gravitational wave events has offered us unique testbeds of gravity in the strong and dynamical field regime. One possible modification to General Relativit…
Implications from GW170817 and I-Love-Q relations for relativistic hybrid stars
Vasileios Paschalidis, Kent Yagi, David Alvarez-Castillo +2
Gravitational wave observations of GW170817 placed bounds on the tidal deformabilities of compact stars allowing one to probe equations of state for matter at supranuclear densitie…
The Gravitational Wave Stress-Energy (pseudo)-Tensor in Modified Gravity
Alexander Saffer, Nicolas Yunes, Kent Yagi
The recent detections of gravitational waves by the advanced LIGO and Virgo detectors open up new tests of modified gravity theories in the strong-field and dynamical, extreme grav…
I-Love-Q Relations for Neutron Stars in dynamical Chern Simons Gravity
Toral Gupta, Barun Majumder, Kent Yagi +1
Neutron stars are ideal to probe, not only nuclear physics, but also strong-field gravity. Approximate universal relations insensitive to the star's internal structure exist among…
Gravitational wave spectroscopy of binary neutron star merger remnants with mode stacking
Huan Yang, Vasileios Paschalidis, Kent Yagi +3
A binary neutron star (BNS) merger event has recently been observed in gravitational waves (GWs). As in the case of binary black holes, GWs generated by BNS consist of inspiral, me…
Black hole perturbation under 2 + 2 decomposition in the action
Justin L. Ripley, Kent Yagi
Black hole perturbation theory is useful for studying the stability of black holes and calculating ringdown gravitational waves after the collision of two black holes. Most previou…
