GWDAW-8 Abstract: Network analysis for coalescing binaries: coherent vs coincidence based strategies

Andrea Viceré · U. Urbino · Virgo


The goal of the talk is to compare the coherent and the coincidence based approaches to the detection of coalescing binaries events by a network of interferometer. While it is patent that the coherent analysis guarantees the optimal performance in terms of detection probability vs false alarm rate, at least in the context of gaussian background noise, it is not completely clear, on quantitative grounds, how less effective would be a coincidence based analysis, possibly improved by a coherent follow-up on the candidates. In the talk I will select a few exemplary cases, in the context of the near future network of interferometric detectors, and perform through these examples a comparison which can help planning the future analyses.
