Scattered light noise at LIGO Livingston Observatory during O4

Anamaria Effler, Debasmita Nandi, Gabriela Gonz\'alez, Huyen Pham, Robert Schofield, Siddharth Soni, Tabata Aira Ferreira, Timothy O'Hanlon, V. V. Frolov

High-SNR scattered light glitches at LIGO Livingston are driven solely by microseismic ground motion at the corner station in the X direction.

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

High-SNR scattered light glitches are modulated solely by microseismic ground motion at the corner station along the X direction; low-SNR glitches are modulated by 10-30 Hz vertical ground motion through a specific vacuum chamber; baffles and an isolation platform produced significant reductions.

C2weakest assumption

That the observed statistical correlations between specific ground-motion channels and glitch rates demonstrate direct causal coupling mechanisms rather than indirect or coincidental associations.

C3one line summary

Scattered light glitches at LIGO Livingston during O4 were traced to microseismic and high-frequency ground motions and mitigated by baffles and seismic isolation.
