SKACH Winter Meeting 2026

26 Jan 2026, 09:00 → 27 Jan 2026, 18:00 Europe/Zurich

Ground Floor E4 (CSCS LCA main Building )

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

We are pleased to invite you to participate to the SKACH Winter Meeting hosted by our collaborators at the Swiss National Supercomputing Centre (CSCS). This event will focus on consortium-wide updates, and updates from the five SKACH programs: Comms & Outreach, Instrumentation, Computing Platforms & Infrastructure, Data Science & Simulations and Science (AstroSignals).

SKACH is primarily funded by the State Secretariat for Education, Research and Innovation (SERI), and is responsible for managing the Swiss contribution to the SKAO. SKACH also leverages funding from external grants such as AstroSignals SINERGIA, SNF Bilateral, PASC, InnoSuisse, and Horizon Europe.

This endeavor is lead by a strong contingent of Swiss institutions; including, Universität Basel (UniBas), Fachhochschule Nordwestschweiz (FHNW), Universität Zürich (UZH), Eidgenössische Technische Hochschule Zürich (ETHZ), École Polytechnique Fédérale de Lausanne (EPFL), Zürcher Hochschule für Angewandte Wissenschaften (ZHAW), Université de Genève (UniGE), Haute École spécialisée de Suisse Occidentale (HES-SO) and the Centro Svizzero di Calcolo Scientifico (CSCS).
