Realtime Follow-up of External Alerts with the IceCube Supernova Data Acquisition System

Abstract

The IceCube Neutrino Observatory is uniquely sensitive to MeV neutrinos emitted during a core-collapse supernova. The Supernova Data Acquisition System (SNDAQ) monitors in real-time the detector rate deviation searching for bursts of MeV neutrinos. We present a new analysis stream that uses SNDAQ to respond to external alerts from gravitational waves detected in LIGO-Virgo-KAGRA.Comment: 6 pages, 5 figures.
