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…

Multi-messenger flare in the quasar PKS 0446+11

Y. Y. Kovalev, M. F. Aller, A. K. Erkenov +15

The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. We investigate a prominent multi-messenger flare in the quasar PKS 1424+240…

Atmospheric neutrino constraints on Lorentz invariance violation with the first six detection units of KM3NeT/ORCA

KM3NeT Collaboration, O. Adriani, A. Albert +294

Lorentz invariance is a fundamental symmetry underlying both the Standard Model of particle physics and General Relativity. Testing its validity provides a direct means of searchin…

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 an eV-scale sterile neutrino with the first six detection units of KM3NeT/ORCA

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

The existence of an eV-scale sterile neutrino has been proposed to explain several anomalous experimental results obtained over the course of the past 25 years. The first search fo…

Extreme Jet Beaming Observed in Neutrino-Associated Blazars

Alexander V. Plavin, Yuri Y. Kovalev, Sergey V. Troitsky

Bright blazars were found to be prominent neutrino sources, and a number of IceCube events were associated with them over recent years. A particularly strong observational connecti…
