| « Spin-precessing gravitational waveforms: an analytic perspective » |
|
A. Klein |
| Spin-induced precession is an important phenomenon to describe for gravitational waveform modelling. From the data analysis point of view, it can break degeneracies present in the signal, allowing us to make more precise measurements of the parameters of the system emitting it. Until recently, no non-trivial analytic solution to the precession equations was known, making necessary the use of computationally costly numerical solutions. A recent solution has been found, and I will describe a fully analytic waveform based on this solution, valid for arbitrary spin configurations. |
