- 요약Multi-messenger astrophysics is a powerful tool for understanding the most energetic particle accelerators in the universe. Although IceCube has discovered a flux of extragalactic neutrinos, the sources of the vast majority of those neutrinos remain a mystery. Several classes of astrophysical transients are proposed sources of neutrino emission. By searching for neutrinos from these sources in real time, we can identify multi-messenger sources rapidly to inform follow-up by other telescopes. In this thesis, a broad range of transients are analyzed, including gravitational wave transients, supernovae, novae, and bright gamma-ray bursts. Compact object mergers, detected by the LIGO-Virgo-KAGRA detectors, may produce neutrinos alongside their gravitational wave emission. Neutrino events are hundreds of times better localized than gravitational wave events. Searching for neutrinos in real time from these sources can inform follow-up by other observatories, increasing the probability of identifying the multi-messenger source. Another exciting transient event is the brightest gamma-ray burst ever observed, GRB 221009A. We search for neutrinos from this GRB in real time and in an archival search leveraging the full energy capabilities of the IceCube detector. We set the strongest constraints on neutrino emission from GRBs using this single burst due to its bright electromagnetic flux and IceCube's non-detection. Finally, we search for sub-TeV neutrinos from nearby and bright novae in archival data and in real time. In archival data, we search for neutrinos from the nova RS Ophiuchi during its 2021 outburst, the only nova so far detected up to TeV gamma-ray energies. This analysis can be applied to the upcoming eruption of nova T Coronae Borealis, which is both closer and expected to be brighter in optical flux than RS Oph, meaning its expected neutrino emission would be several times higher than that of RS Oph. IceCube will be able to search for neutrino emission from this nova in real time using two neutrino datasets spanning GeV-PeV neutrino energies.
