Detecting Galactic core-collapse supernovae with the IceCube neutrino telescope — •Alexander Fritz for the IceCube collaboration — Johannes-Gutenberg Universität Mainz

The IceCube neutrino telescope is sensitive to the large flux of neutrinos from galactic core-collapse supernovae. In fact, for distances up to the Magellanic Clouds, IceCube will provide the smallest uncertainties world-wide on the time evolution of the neutrino flux and will roughly measure the average neutrino energy. Thanks to a tight monitoring and error recovery functionality, the detector uptime runs at 99.8% around the clock. I will summarize recent improvements in the data acquisition, monitoring, reconstruction and simulation. I will also discuss the effect of the neutrino mass on neutrino light curves and how a combined analysis of gravitational waves and neutrinos from supernovae may allow to study instabilities in the explosion mechanism, such as the standing accretion shock instability (SASI)
