Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A

KM3NeT Collaboration, O. Adriani, A. Albert +278

Context: The detection of the highest energy neutrino observed to date by KM3NeT, with an estimated energy of 220 PeV, opens up new possibilities for the study and identification o…

Optimizing the potential of KM3NeT in detecting core-collapse supernovae

KM3NeT Collaboration, O. Adriani, A. Albert +285

Core-collapse supernovae mark the end of life of massive stars. However, despite their importance in astrophysics, their underlying mechanisms remain unclear. Neutrinos that emerge…

Search for steady and flaring neutrino emission from cosmic sources using the complete ANTARES dataset

ANTARES Collaboration, A. Albert, S. Alves +139

ANTARES, a neutrino detector located in the depths of the Mediterranean Sea, operated successfully for over 15 years before being decommissioned in 2022. The telescope offered an i…
