The Memory Remains (Undetected): Updates from the Second LIGO/Virgo Gravitational-Wave Transient Catalog. (arXiv:2105.02879v1 [gr-qc]) <a href="http://arxiv.org/find/gr-qc/1/au:+Hubner_M/0/1/0/all/0/1">Moritz Hübner</a>, <a href="http://arxiv.org/find/gr-qc/1/au:+Lasky_P/0/1/0/all/0/1">Paul Lasky</a>, <a href="http://arxiv.org/find/gr-qc/1/au:+Thrane_E/0/1/0/all/0/1">Eric Thrane</a> The LIGO and Virgo observatories have reported 39 new gravitational-wave detections during the first part of the third observation run, bringing the total to 50. Most of these new detections are consistent with binary black-hole coalescences, making them suitable targets to search for gravitational-wave memory, a non-linear effect of general relativity. We extend a method developed in previous publications to analyse these events to determine a Bayes factor comparing the memory hypothesis to the no-memory hypothesis. Specifically, we calculate Bayes factors usingRead More →
