Ice-Cube is a cubic kilometer neutrino detector embedded in the deep glacial ice at the South Pole. Starting in 2014, the detector has observed a diffuse flux of astrophysical neutrinos in the TeV-PeV energy range. This talk will summarize the various searches performed for the sources of these neutrinos. All sky un-triggered searches are performed, looking for the serendipitous discovery of time integrated and flaring sources, while stacking searches target specifi c catalogs of promising source candidates such as Supernova Remnants and Blazars. Cross correlation searches seek to identify common sources of neutrinos and other messengers such as ultra-high energy cosmic rays. A real-time alert system enables quick follow-up observations by other multi-messenger observatories, leading to the identifi cation of neutrinos from a flaring blazar in 2018. I will explore the implications of these observations for models of cosmic ray acceleration, and the future of neutrino astronomy at the South Pole.
