Gravitational-wave echoes from numerical-relativity waveforms via space-time construction near merging compact objects
Sizheng Ma, Qingwen Wang, Nils Deppe +7
We propose a new approach toward reconstructing the late-time near-horizon geometry of merging binary black holes, and toward computing gravitational-wave echoes from exotic compac…
Universal features of gravitational waves emitted by superkick binary black hole systems
Sizheng Ma, Matthew Giesler, Vijay Varma +2
We use numerical relativity to study the merger and ringdown stages of "superkick" binary black hole systems (those with equal mass and anti-parallel spins). We find a universal wa…
Gravitational-wave echoes from spinning exotic compact objects: numerical waveforms from the Teukolsky equation
Shuo Xin, Baoyi Chen, Rico K. L. Lo +7
We present numerical waveforms of gravitational-wave echoes from spinning exotic compact objects (ECOs) that result from binary black hole coalescence. We obtain these echoes by so…
Extending superposed harmonic initial data to higher spin
Sizheng Ma, Matthew Giesler, Mark Scheel +1
Numerical simulations of binary black holes are accompanied by an initial spurious burst of gravitational radiation (called `junk radiation') caused by a failure of the initial dat…
Detecting resonant tidal excitations of Rossby modes in coalescing neutron-star binaries with third-generation gravitational-wave detectors
Sizheng Ma, Hang Yu, Yanbei Chen
Rossby modes (r-modes) of rotating neutron stars can be excited by the gravitomagnetic forces in coalescing binary systems. The previous study by Flanagan and Racine [Phys. Rev. D…
Spin and Eccentricity Evolution in Triple Systems: from the Lidov-Kozai Interaction to the Final Merger of the Inner Binary
Hang Yu, Sizheng Ma, Matthew Giesler +1
We study the spin and eccentricity evolution of black-hole (BH) binaries that are perturbed by tertiary masses and experience the Lidov-Kozai (LK) excitation. We focus on three asp…
