This paper addresses the computational challenges of detecting Mini-Extreme-Mass-Ratio Inspirals (mini-EMRIs) using ground-based gravitational wave detectors. The authors develop a new method, ΣTrack, that overcomes limitations of existing semi-coherent methods by accounting for spectral leakage and optimizing coherence time. This is crucial for detecting signals that evolve in frequency over time, potentially allowing for the discovery of exotic compact objects and probing the early universe.
Key Takeaways
- •Develops a new method (ΣTrack) to detect mini-EMRIs, overcoming limitations of existing methods.
- •Addresses spectral leakage issues in gravitational wave data analysis.
- •Introduces the ΣR statistic for improved signal detection.
- •Demonstrates an order-of-magnitude enhancement in detection volume.
- •The method is applicable to future space-based gravitational wave detectors.
