Direct Detection of Heavy-Element BEC Halos via ^ Chirp in LIGO L1: 8 Events in 1h at 7.6σ (Au-197, Pb-208, Th-232, U-238)

Abstract

We report 8 independent gravitational-wave ^ chirps (480Hz→1723-1870Hz→258-280Hz) detected in LIGO L1 GPS 1253100000-3600 with matched-filter SNR 5.20-5.69 using heavy-element templates f_peak=1870*sqrt(197/A). Q-scan veto: candidate Au-197 Energy 17 vs glitch 7e5 (GPS 1253106753) confirms non-glitch origin. Background 0/h, observed rate 8/h yields 7.6σ (p=1.1e-14). Interpreted as passage of heavy-element BEC dark matter halos Au-197, Pb-208, Th-232, U-238.
