Swiss SKA Days 2022

3 Oct 2022, 09:30 → 4 Oct 2022, 17:05 Europe/Zurich

USI, Lugano

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

We are pleased to invite you to participate to the sixth edition of the Swiss SKA days. During this exciting 2-day event we will discuss the ambitious SKA radio-astronomy project at the forefront of advanced technology and computing.

The Square Kilometer Array (SKA) 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 2022 will discuss the Swiss interest and participation in this ambitious project.

The sixth Swiss SKA meeting will take place during October 3 to 4 at USI (Università della Svizzera italiana) in Lugano at the kind invitation of CSCS (Swiss National Supercomputing Centre).
