“…Without the need for complex inner boundary conditions, the puncture approach is potentially easier to implement than excision. CTS-puncture binary black-hole initial data would provide a useful comparison with excision data results, and also allow evolution codes that employ punctures [18,19,20] to take advantage of CTS data.…”

We apply the puncture approach to conformal thin-sandwich black-hole initial data. We solve numerically the conformal thin-sandwich puncture (CTSP) equations for a single black hole with non-zero linear momentum. We show that conformally flat solutions for a boosted black hole have the same maximum gravitational radiation content as the corresponding Bowen-York solution in the conformal transverse-traceless decomposition. We find that the physical properties of these data are independent of the free slicing parameter.

“…The equal-mass runs were carried out with our Hahndol evolution code [32] using the Paramesh meshrefinement infrastructure [33]. The new X4 00 data, however, uses Hahndol paired with the Einstein Toolkit [34] release of the Cactus Computational Toolkit [35] and the Carpet mesh-refinement driver [36].…”

We conduct a descriptive analysis of the multipolar structure of gravitational-radiation waveforms from equal-mass aligned-spin mergers, following an approach first presented in the complementary context of nonspinning black holes of varying mass ratio [1]. We find that, as with the nonspinning mergers, the dominant waveform mode phases evolve together in lock-step through inspiral and merger, supporting the previous waveform description in terms of an adiabatically rigid rotator driving gravitational-wave emission -an implicit rotating source (IRS). We further apply the latetime merger-ringdown model for the rotational frequency introduced in [1], along with an improved amplitude model appropriate for the dominant (2, ±2) modes. This provides a quantitative description of the merger-ringdown waveforms, and suggests that the major features of these waveforms can be described with reference only to the intrinsic parameters associated with the state of the final black hole formed in the merger. We provide an explicit model for the merger-ringdown radiation, and demonstrate that this model agrees to fitting factors better than 95% with the original numerical waveforms for system masses above ∼ 150M⊙. This model may be directly applicable to gravitational-wave detection of intermediate-mass black hole mergers.

Excising das All: Evolving Maxwell waves beyond scri

We study the numerical propagation of waves through future null infinity in a conformally compactified spacetime. We introduce an artificial cosmological constant, which allows us some control over the causal structure near null infinity. We exploit this freedom to ensure that all light cones are tilted outward in a region near null infinity, which allows us to impose excision-style boundary conditions in our finitedifference code. In this preliminary study we consider electromagnetic waves propagating in a static, conformally compactified spacetime.
