abstract
Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for the astronomical community might make it possible to observe the onset of electromagnetic emission from (CBC). We demonstrate a computationally practical filtering strategy that could produce early-warning triggers before gravitational radiation from the final merger has arrived at the detectors.

A gauge-theoretic framework models the whitening filter as a section of a principal bundle and proves that the minimum-phase connection is flat for scalar fields, yielding a holonomic update law determined only by the instantaneous noise state.
Targeted eccentric search detects GW200105 with SNR 13.4 and FAR <1/1000 yr, consistent with dynamical formation of the NSBH binary.
New GstLAL offline methods reuse online matched-filtering products, merge with a heavy black hole search, revise the likelihood ratio and background estimation, and deliver a 50-100% sensitivity gain for high-mass events on a tested O3 data segment while improving reusability and reducing compute.
KAGRA enhances sky localization of binary neutron star mergers in the LVK network via added baselines, with measurable gains at current sensitivity and larger improvements as range reaches ~30 Mpc.
