Over the threshold: Application for Multimessenger Searches using High-Energy Neutrinos and Gravitational-Wave Candidates Below the Detection Limit

Gravitational-wave (GW) emission from cosmic sources can be accompanied by other messengers across the electromagnetic spectrum, as well as by particles such as high-energy neutrinos (HENs). Joint gravitational-wave -- high-energy neutrino sources can be discovered by searching subthreshold events in both data streams as time and spatially coincident GW+HEN candidates may rise above the detection threshold. Here we present the application of the Low-Latency Algorithm for Multimessenger Astrophysics (LLAMA) pipeline for joint searches for common sources of gravitational-waves and high-energy neutrinos using subthreshold data streams.
