Antonio Marinelli, Pasquale Migliozzi, Andreino Simonelli

TL;DR
This paper proposes a large-scale undersea acoustic detector in the Adriatic Sea, utilizing existing offshore platforms to observe ultra-high-energy cosmic neutrinos through thermo-acoustic signals, complementing radio detection methods.
Contribution
It introduces a novel undersea acoustic neutrino observatory concept using existing infrastructure and ray tracing analysis to enhance ultra-high-energy neutrino detection capabilities.
Findings
Design of a 10,000 km² acoustic array in the Adriatic Sea.
Potential to detect ultra-high-energy cosmic neutrinos for the first time.
Complementary to radio array detectors, reducing thermo-acoustic noise.
Abstract
The existence of cosmic accelerators able to emit charged particles up to EeV energies has been confirmed by the observations made in the last years by experiments such as Auger and Telescope Array. The interaction of such energetic cosmic-rays with gas or low energy photons, surrounding the astrophysical sources or present in the intergalactic medium, guarantee an ultra-high-energy neutrino related emission. When these energetic neutrinos interact in a medium produce a thermo-acoustic process where the energy of generated particle cascades can be conveyed in a pressure pulse propagating into the same medium. The kilometric attenuation length as well as the well-defined shape of the expected pulse suggest a large-area-undersea-array of acoustic sensors as an ideal observatory. For this scope, we propose to exploit the existing and no more operative offshore (oil rigs) powered platforms…
