Four months ago we published the exciting #KM3NeT_UHE #RecordNeutrino #KM3230213A in @nature.com
The scientific community is eagerly working on understanding this observation. Beside our 5 companion papers, almost 30 papers have been published in a broad range of topics:

In KM3NeT, we use light to "see the invisible".
This display shows #KM3230213A, our ultra-high-energy neutrino. Each sphere shows #Cherenkov #light detected deep under the sea, with colours representing when the light arrived.

A new companion paper is out (No.5)!📜🔔
It tests Lorentz symmetry via high-energy neutrino analysis using our #KM3230213A, setting the tightest limit on neutrino speed vs. light speed (less than 1 part in 10^21)

A new paper is out!📜🔔
The paper investigates the possible cosmogenic origin of #KM3230213A evaluating different evolutions of cosmic ray sources. The plot shows the expected neutrino fluxes for various evolutions of the sources.

A new paper is out! 📜 🔔
The paper investigates the possible galactic origin of #KM3230213A, concluding that it is very unlikely due to the lack of sources and the required energies.

A new paper is out!📜🔔
The paper compares #KM3230213A within the global neutrino landscape to IceCube and Auger data. It explores flux models, and this plot displays the constraints on single power-law flux.
