Embedded software of the KM3NeT Central Logic Board

This KM3NeT technical paper describes the embedded software running in the data acquisition of the telescope. Located in the deep Mediterranean Sea, the hardware of the telescope is not directly accessible. The implemented software facilitates remote management of the deployed hardware and safe reconfiguration of firmware. It runs on the central electronics board of each optical module of the KM3NeT detectors. This central logic board coordinates the readout of all equipment inside the module and manages the communication and data transmission over optical fibers connecting the module to the control station on shore.

KM3NeT neutrino follow-up of gravitational wave sources

In this paper the KM3NeT Collaboration reports the results of a neutrino follow-up study made with ORCA data of gravitational wave sources detected by LIGO-Virgo in 2019-2020. The search focuses both on MeV neutrinos and high-energy neutrinos. No significant excess was observed for any of the sources.

Upper limits on the neutrino emission from individual sources and the typical emission from binary black hole mergers are computed and compared with the constraints from other neutrino telescopes.

Since May 2023, the Collaboration is performing real-time follow-ups of the GW triggers detected by LIGO-Virgo-KAGRA in their fourth observing run, with both ORCA and ARCA detectors with much larger instrumented volumes than in the previous searches.

In the figure the comparison of 90% upper limits on the neutrino fluence from gravitational wave sources for ANTARES, IceCube, Super-Kamiokande and KM3NeT.
