Realtime multimessenger astronomy with IceCube & ULTRASAT

Streszczenie:
During the last years we have witnessed several breakthroughs in the field of astroparticle physics and astronomy, ranging from the detection of optical counterparts of the gravitational wave sources to the first likely identification of a source of high-energy cosmic neutrinos – a bright gamma-ray Blazar. Most recently, high-energy neutrino detected by IceCube were traced back to a Tidal-Disruption Event (with ~3 sigma significance), providing first evidence that these objects might be the sights of extreme particle acceleration. In my talk I will discuss the multimessenger techniques, the significance of these neutrino associations and what we can say about the sources of cosmic neutrinos neutrinos. I will then turn to the future ULTRASAT telescope, that will launch in 2025 to provide unique survey capacities in the UV, and with that, promises to enable a new chapter in transient multimessenger astronomy.
