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.
