GNN Meeting 2026

May 25–26, 2026 — Nikhef, Amsterdam, The Netherlands

The GNN Meeting 2026 (formerly MANTS) will be held at Nikhef in Amsterdam. This annual meeting brings together all neutrino collaborations which constitute the GNN, fostering the exchange between collaborations to best exploit synergies from hardware developments to high-level analyses to future visions. Nikhef is well connected by public transport, approximately 15 minutes from Amsterdam Centrum.

MACROS 2026

April 23–24, 2026 — Penn State Pattee Library, University Park, PA, USA

MACROS 2026 is a high-energy neutrino astrophysics workshop hosted by Penn State’s Institute for Gravitation and Cosmos (IGC) under its new Multimessenger Astrophysics of High-Energy Cosmic Neutrinos Focus Initiative (NuMMA FI). This two-day workshop has a strong focus on early career researchers (ECRs), with all invited speakers and committee members being ECRs. The workshop features invited talks followed by panel-led and audience-led discussions. Researchers of all career stages are welcome.

Topics include: astrophysics with high-energy neutrinos, UHE neutrino discovery, and BSM physics with cosmic neutrinos.

There is no registration fee. Registration and more information: https://events.icecube.wisc.edu/e/macros2026

GNN Meeting Series

The annual GNN Meeting (formerly the Mediterranean-Antarctic Neutrino Telescope Symposium, MANTS*) emerged as a meeting between the IceCube and ANTARES communities. Its aim is to discuss latest results, exchange technical information (like e.g. event reconstruction, Monte Carlo simulations etc.). The meeting has developed into a global meeting according to the spirit of GNN: it includes scientists from all Mediterranean projects, from Lake Baikal and from IceCube. Since unpublished information is presented, the websites are accessible only via a password.

* The GNN Meeting series was known as the MANTS (Mediterranean-Antarctic Neutrino Telescope Symposium) conferences until 2024, when the series was renamed to reflect the broader, global scope of the network.

VLVNT Workshop Series

The biannual VLVNT Workshop (VLVNT stands for Very Large Volume Neutrino Telescopes) is devoted to the physics and technical aspects of very large volume neutrino telescopes. Partners in the discussions are the neutrino telescope communities and representatives of industries relevant for building very large neutrino telescopes. Originally, the scope was limited to the technical design of a neutrino telescope in the Mediterranean Sea; since 2008, it has been extended to include results and future plans of neutrino telescopes at the Antarctic and in Lake Baikal.
