Inpainting over the cracks: challenges of applying pre-merger searches for massive black hole binaries to realistic LISA datasets

Gareth Cabourn Davies, Ian Harry

Inpainting recovers 14 pre-merger massive black hole binary signals in realistic LISA data even with gaps.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We demonstrate the successful recovery of the 14 signals in the dataset that we expected to be identifiable at least half a day before merger. The inpainting method can identify premerger signals even when gaps are present in the data, demonstrating the recovery of a signal even when 3 day-long data gaps are added to the 14 days preceding merger.

C2weakest assumption

That the simulated Sangria-HM dataset accurately models the challenges of real LISA observations, including noise and signal properties, without introducing biases that would not occur in actual data.

C3one line summary

Inpainting allows recovery of pre-merger massive black hole binary signals in LISA data despite gaps and overlaps.
