Description
A wide variety of transient phenomena, including gamma-ray bursts, supernovae, and novae, are expected to emit GeV neutrinos. Detecting these neutrinos provides unique insights into their emission mechanisms and particle acceleration processes. IceCube Upgrade, the densest infill array in IceCube Neutrino Observatory, features newly developed multi-PMT optical modules with close spacing. It was deployed in 2026 and is currently under commissioning. IceCube Upgrade is expected to provide a significant improvement in sensitivity for transient searches in the GeV energy range. In this contribution, we present the performance of our event selection targeting GeV neutrino transients, as well as prospects for the analysis of initial data from IceCube Upgrade.
