The scalar Green function of the Kerr spacetime
Huan Yang, Fan Zhang, Aaron Zimmerman +1
In this paper we study the scalar Green function in the Kerr spacetime using WKB methods. The Green function can be expressed by Fourier-transforming to its frequency-domain counte…
A joint approach for reducing eccentricity and spurious gravitational radiation in binary black hole initial data construction
Fan Zhang, Béla Szilágyi
At the beginning of binary black hole simulations, there is a pulse of spurious radiation (or junk radiation) resulting from the initial data not matching astrophysical quasi-equil…
Parameter Estimation of Gravitational Waves from Nonprecessing BH-NS Inspirals with higher harmonics: Comparing MCMC posteriors to an Effective Fisher Matrix
R. O'Shaughnessy, B. Farr, E. Ochsner +3
Using the \texttt{lalinference} Markov-chain Monte Carlo parameter estimation code, we examine two distinct nonprecessing black hole-neutron star (BH-NS) binaries with and without…
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO, Advanced Virgo and KAGRA
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1319
We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years,…
