  • Parameter inference

Research summary

Overlapping massive-black-hole-binary signals can affect parameter recovery in Taiji observations. This study uses population simulations, Fisher-matrix estimates, and Bayesian analyses to investigate source confusion. It examines how overlap changes uncertainties and how higher-order waveform modes help resolve degeneracies, providing guidance for inference with multiple signals in space-based detector data.

Extended notes

The analysis studies overlap in both time and frequency. It compares waveform models to assess how higher-order modes change the inference consequences of source confusion.
