New self-force method via elliptic partial differential equations for Kerr inspiral models Open
We present a new method designed to avoid numerical challenges that have impeded calculation of the Lorenz gauge self-force acting on a compact object inspiraling into a Kerr black hole. This type of calculation is valuable in creating wav…
Highly eccentric EMRI waveforms via fast self-forced inspirals Open
We present new developments and comparisons of competing inspiral and waveform models for highly eccentric non-spinning extreme and intermediate mass-ratio inspirals (EMRIs and IMRIs). Starting from our high eccentricity self-force library…
Lorenz gauge gravitational self-force calculations of eccentric binaries using a frequency domain procedure Open
We present an algorithm for calculating the metric perturbations and gravitational self-force for extreme-mass-ratio inspirals (EMRIs) with eccentric orbits. The massive black hole is taken to be Schwarzschild and metric perturbations are …
Fast spectral source integration in black hole perturbation calculations Open
This paper presents a new technique for achieving spectral accuracy and fast computational performance in a class of black hole perturbation and gravitational self-force calculations involving extreme mass ratios and generic orbits. Called…
Reissner-Nordström perturbation framework with gravitational wave applications Open
We present a new convenient framework for modeling Reissner-Nordstr\"om black hole perturbations from charged distributions of matter. Using this framework, we quantify how gravitational wave observations of compact binary systems would be…
Evolution of small-mass-ratio binaries with a spinning secondary Open
We calculate the evolution and gravitational-wave emission of a spinning compact object inspiraling into a substantially more massive (non-rotating) black hole. We extend our previous model for a non-spinning binary [Phys. Rev. D 93, 06402…
Highly eccentric inspirals into a black hole Open
We model the inspiral of a compact stellar-mass object into a massive nonrotating black hole including all dissipative and conservative first-order-in-the-mass-ratio effects on the orbital motion. The techniques we develop allow inspirals …
Repeated faint quasinormal bursts in extreme-mass-ratio inspiral waveforms: Evidence from frequency-domain scalar self-force calculations on generic Kerr orbits Open
We report development of a code to calculate the scalar self-force on a scalar-charged particle moving on generic bound orbits in the Kerr spacetime. The scalar self-force model allows rapid development of computational techniques relevant…
Extreme-mass-ratio inspirals into a black hole Open
The inspiral of a compact stellar-mass object (black hole, neutron star, or white dwarf) into a super-massive black hole is modeled perturbatively. All dissipative and conservative effects on the orbital motion are included up to first-ord…

Scalar self-force for generic bound orbits on Kerr Open
We perform scalar self-force calculations for inclined, eccentric orbits of a small, compact body in Kerr spacetime. To implement these calculations with arbitrary numerical precision, we generalize spectral source integration (SSI) techni…
