ICRC 2025 Neutrino Rapporteur Talk

I recently gave the closing rapporteur track of the neutrino track at the 39th International Cosmic Ray Conference (ICRC 2025), held in Geneva during July 14-24, 2025. The goal was to summarize and highlight the contributions presented in the neutrino track throughout the conference, both in plenary and parallel talks.

It was plenty of work, but very rewarding. Here is my opening slide:

This is a slide summarizing the current state of the measurement of the TeV-PeV diffuse neutrino flux, including the new IceCube MESE measurement presented at the conference:

Finally, this was a good opportunity to look back to ten years ago, and to what I was thinking at the time, just a couple of years after the discovery of PeV neutrinos by IceCube:

Wrap-up of the 2025 NBI Neutrino School

The IV NBI PhD Summer School on Neutrinos has wrapped!

From July 7 to 11, 2025, we hosted 53 PhD, MSc, and BSc students from around the world. They received lectures on neutrino theory & phenomenology, neutrino astrophysics, and neutrino cosmology. All in all, we had 9 lectures, 5 topical seminars from NBI locals, and 24 student talks.

Here are a few photos (photo credit to co-organizer Markus Ahlers):

Like for the 2021, 2022, and 2023 schools, all the videos from the school are available on our YouTube channel.

IV NBI Neutrino Summer School “Here, There & Everywhere”

Registration is now open for the fourth edition of our NBI Neutrino Summer School, “Here, There & Everywhere”.

Like in previous editions (2021, 2022, 2023), the school is aimed at PhD students and advanced MSc students from all over the world that work on neutrinos, are planning to work on them, or are simply interested in them! The school is a one-week series of lectures on neutrino phenomenology, astrophysics, and cosmology delivered by carefully chosen world experts on these subjects.

When? July 7-11, 2025

Where? Niels Bohr Institute, Copenhagen, Denmark
