Closed-form solutions of spinning, eccentric binary black holes at 1.5 post-Newtonian order
Rickmoy Samanta, Sashwat Tanay, Leo C. Stein
The closed-form solution of the 1.5 post-Newtonian (PN) accurate binary black hole (BBH) Hamiltonian system has proven to be difficult to obtain for a long time since its introduct…
Nonlinearities in Black Hole Ringdowns
Keefe Mitman, Macarena Lagos, Leo C. Stein +11
The gravitational wave strain emitted by a perturbed black hole (BH) ringing down is typically modeled analytically using first-order BH perturbation theory. In this Letter we show…
Fixing the BMS frame of numerical relativity waveforms with BMS charges
Keefe Mitman, Leo C. Stein, Michael Boyle +8
The Bondi-van der Burg-Metzner-Sachs (BMS) group, which uniquely describes the symmetries of asymptotic infinity and therefore of the gravitational waves that propagate there, has…
Gravitational-wave energy and other fluxes in ghost-free bigravity
Alexander M. Grant, Alexander Saffer, Leo C. Stein +1
One of the key ingredients for making binary waveform predictions in a beyond-GR theory of gravity is understanding the energy and angular momentum carried by gravitational waves a…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Tidally-induced nonlinear resonances in EMRIs with an analogue model
David Bronicki, Alejandro Cárdenas-Avendaño, Leo C. Stein
One of the important targets for the future space-based gravitational wave observatory LISA is extreme mass ratio inspirals (EMRIs), where long and accurate waveform modeling is ne…
