Inertial bioluminescence rhythms at the Capo Passero (KM3NeT-Italia) site, Central Mediterranean Sea

Jacopo Aguzzi, Emanuela Fanelli, Tiziana Ciuffardi, Antonio Schirone et autres

In the deep sea, the sense of time is dependent on geophysical fluctuations, such as internal tides and atmospheric-related inertial currents, rather than day-night rhythms. Deep-sea neutrino telescopes instrumented with light detecting Photo-Multiplier Tubes (PMT) can be used to describe the synchronization …

Measurement of the atmospheric muon flux at 3500 m depth with the NEMO Phase-2 detector

Carla Distefano, S. Aiello, F. Ameli, Marco Anghinolfi et autres

In March 2013, the Nemo Phase-2 tower was successfully deployed at 80 km off-shore Capo Passero (Italy) at 3500 m depth. The tower operated continuously until August 2014. We present the results of the atmospheric muon analysis from the data collected in …

Underwater acoustic positioning system for the SMO and KM3NeT - Italia projects

Salvatore Viola, S. Aiello, F. Ameli, Marco Anghinolfi et autres

In the underwater neutrino telescopes, the positions of the Cherenkov light sensors and their movements must be known with an accuracy of few tens of centimetres. In this work, the activities of the SMO and KM3NeT-Italia teams for the development of an …
