Time-dependent neutrino emission searches in IceCube with combined datasets

Transient neutrino sources are primary candidates for high-energy neutrino production, such as blazars, tidal disruption events and gamma-ray bursts. The presence of a neutrino flare from the direction of TXS 0506+056 suggests that not all neutrinos are accompanied by a gamma-ray flare. The absence of gamma-rays may also occur in optically thick sources, where we rely on the temporal data from neutrinos alone. In this work, we perform a time-dependent analysis combining cascades, Northern Sky tracks and starting track event samples to search for neutrino sources and optimize the search time windows. The use of multiple samples allows us to achieve the best all-sky sensitivities. We report on the status of the analysis, which includes the source sensitivities at different declinations, and source spectral indices.
