TL;DR: These are the tests of general relativity that will become possible with space-based gravitational-wave detectors operating in the ∼ 10−5 − 1 Hz low-frequency band and the remarkable richness of astrophysics, astronomy, and cosmology in the low- frequencies make the case even stronger.

TL;DR: In this article, the authors present a detailed description of techniques developed to combine 3D numerical simulations and, subsequently, a single black hole close-limit approximation, making it possible to compute the first complete waveforms covering the post-orbital dynamics of a binary-black-hole system with the numerical simulation covering the essential nonlinear interaction before the close limit becomes applicable for the late time dynamics.

TL;DR: In this article, a simple comparison of the waveforms produced by two very different, but equally successful approaches?the generalized harmonic gauge and the moving puncture methods is presented, with exceptional agreement for the final burst of radiation.

TL;DR: This work uses a technique that combines the full numerical approach to solve the Einstein equations, applied in the truly nonlinear regime, and linearized perturbation theory around the final distorted single black hole at later times to compute the plunge waveforms.

TL;DR: The second round of the Mock Data Challenge (MLDC) as discussed by the authors was the first round of LISA data analysis, and the second round data sets contain radiation from an entire Galactic population of stellar-mass binary systems.
