IceCube – a window onto the universe's most elusive particles

  • Date: 18 November 2025, 17:00–17:45
  • Location: Carolina Rediviva, Tidskriftsläsesalen på Carolina Rediviva, Dag Hammarskjölds Väg 1, Uppsala
  • Type: Lecture
  • Lecturer: Axel Pontén
  • Organiser: Uppsala universitet
  • Contact person: Gisella Bengtsson

Deep beneath the ice at the South Pole lies one of the world’s most unique telescopes – the IceCube Neutrino Observatory.

Please note, the lecture is given in Swedish.

It is not a telescope in the traditional sense, but rather a giant neutrino telescope buried in the clear Antarctic ice, more than two kilometres below the surface. Unlike most telescopes, it does not measure light from stars and galaxies, but some of the universe’s most common yet elusive particles: neutrinos. IceCube helps us understand neutrinos and peer into the most extreme environments in the universe. It is an example of how we can use ice as a tool to understand the cosmos.

Axel Pontén, doctoral student at the Department of Physics and Astronomy, will talk about the mysterious neutrinos and why they are interesting, and show how we can indirectly ‘see’ these ghostly particles with IceCube’s thousands of detector modules buried in the ice. We will also get a glimpse of some of the discoveries that have been made.

Free admission.
