PLEnuM: Prospects of a planetary neutrino observatory system — •Matthias Huber and Elisa Resconi — Technische Universität München, Fakultät für Physik, James-Franck-Str. 1, 85748 Garching, Deutschland

High-energy neutrinos, arriving at the Earth from the farthest reaches of the cosmos have long been thought to hold the key to resolving the cosmic ray riddle. While the first compelling evidence for a correlation between high-energy neutrinos and the blazar TXS 0506+056 was found in 2018, no sources of these neutrinos have been discovered yet. To bring rapid improvements in the sensitivity of cosmic neutrino studies, we propose to launch the Planetary Neutrino Monitoring System (PLEnuM). The concept of PLEnuM is based on the vision to operate a global-scale neutrino telescope network, integrating all neutrino telescopes in progress (KM3NeT, GVD, P-ONE, IceCube). By means of this collaboration, every direction of the Universe becomes observable with local improvements of the sensitivity of factors up to ~160 compared to IceCube. In this talk, I will outline the prospects of cosmic neutrino source searches on the basis of PLEnuM.
