Public Results in O4 from All-Sky Searches
ORAL · Invited
Abstract
The first part of the fourth observing run (O4a) of the LIGO Scientific, Virgo, and KAGRA (LVK) Collaboration took place from May 2023 - January 2024 and saw the observation of more than 70 new gravitational wave candidates from merging black holes and neutron stars. The incredible success of O4a was due to increased detector sensitivity and improved search algorithms, seeing the number of significant public alerts to date nearly double. In this talk, I will provide an overview of results from the all sky search pipelines: cWB, GstLAL, MBTA, SPIIR, and PyCBC. Notable results include new neutron star-black hole binary candidates and a large and diverse population of binary black hole mergers. These new merger candidates will inform our understanding of astrophysical merger rates, binary population properties, and formation mechanisms.
