First call opened for transnational access to KM3NeT data

8 April 2026 – The first call for proposals for science projects based on KM3NeT data proposed by external users is open!

The call and ACME – This call is opened in the framework of ACME. The ACME project enables transnational access (TA) on the basis of scientific merit to a wide range of complementary astroparticle, high-energy and astronomical Research Infrastructures to perform new science of multi-messenger astrophysics.

For more information on ACME see the ACME portal.

How to prepare a proposal – This call is open to all external users, with no restriction. External scientists may act as Principal Investigators (PI) or co-Investigators (coI) on the proposals, provided they agree to a Non-Disclosure Agreement with the KM3NeT collaboration. The proposals will be evaluated in a blind procedure by a Program Committee, comprising members from both KM3NeT and the Pierre Auger Collaborations. The proposals will have to be presented in two documents: a proposal description and a team description.

More information on the call:

The deadline for submission is on May 22nd, 2026, 12:00 UTC.

For all details on how to prepare a proposal, you can check the full text of the call.

Find the template of the two documents to prepare here: templates of proposal and team documents.

Non-disclosure Agreement: NDA template.

Lorentz invariance

10 March 2026 – We present a new paper with the title ‘Atmospheric neutrino constraints on Lorentz invariance violation with the first six detection units of KM3NeT/ORCA’.

In the paper, we describe our search for the violation of isotropic Lorentz invariance using 1.4 years of atmospheric neutrino data collected with ORCA6 – the first six detection units of the ORCA detector. Read more






KM3NeT Bootcamp brings newcomers together

26th January 2026 – The 2026 KM3NeT Bootcamp was held at the Faculty of Science, in Granada, from January 20th to January 23rd, bringing together newcomers to the collaboration for an intensive introduction to KM3NeT. Read more


Blazar origin of KM3-230213A?

21 November 2025 – We present a new paper with the title ‘Blazars as a Potential Origin of the KM3-230213A Event‘.

In the paper, we test the hypothesis that the ultra-high-energy neutrino KM3-230213A could come from the diffuse neutrino emission of blazars. Read more
