Premerger localization of gravitational-wave standard sirens with LISA: Harmonic mode decomposition
Premerger localization of gravitational-wave standard sirens with LISA: Harmonic mode decomposition
The continuous improvement in localization errors (sky position and distance) in real time as LISA observes the gradual inspiral of a supermassive black hole binary can be of great help in identifying any prompt electromagnetic counterpart associated with the merger. We develop a new method, based on a Fourier decomposition …
