Swiss SKA Days 2026

31 Aug 2026, 10:00 → 2 Sept 2026, 15:45 Europe/Zurich

Room 328, 3rd floor (HES-SO/HE-Arc - Neuchâtel)

Joanna Jermini-Howard, Jean-Paul Kneib (EPFL), Carolyn Crichton

We are pleased to invite you to participate to the 10th edition of the Swiss SKA days. During this exciting 3-day event we will discuss the ambitious SKA radio-astronomy project at the forefront of advanced technology and computing.

The program will include the following topics addressed in plenary and parallel sessions:

• Updates on the SKA Observatory and precursor facilities
• SKA Regional Centers
• Astrophysics with the SKA and precursors
• Computing, Simulations, Data Science and more...

The Square Kilometer Array Observatory (SKAO) project is an international effort to build the world’s largest radio telescope, with eventually over one square kilometer of collecting area in South Africa and Australia. The SKA Days 2026 will discuss the Swiss interest and participation in this ambitious project.

The 10th Swiss SKA meeting will take place from Monday 31 August 2026 to Wednesday 2 September 2026 in Neuchâtel on the campus of HES-SO/HE-Arc.
