GeneralizedSasakiNakamura.jl
Black-hole perturbation theory
Julia tools for Kerr perturbation calculations, including homogeneous solutions and source-driven inhomogeneous workflows connected to frequency-domain waveform and flux production.
Tools
KerrGeodesics.jl
Relativistic orbital dynamics
Bound timelike Kerr geodesics parameterized by orbital elements, supplying orbital frequencies, phases, and trajectories for EMRI and b-EMRI waveform pipelines.
AdaptiveLevin.jl
Numerical algorithms
Adaptive Levin methods for one- and two-dimensional highly oscillatory integrals, useful when high-eccentricity source terms develop rapidly oscillating high-frequency structure.
