Description
Overview
The Cosmology in the Alps Conference focuses on radio cosmology studying the universe on large scales. It aims to bring together experts in the field together with early career researchers to foster interactions.
Cosmology in the Alps focuses on three main goals:
●Foster developments in radio Cosmology
●Highlight young researchers in Cosmology from across the globe
●Highlight Swiss contributions to the global Cosmology landscape
The conference will be held at the Hotel Glacier in Les Diablerets, in the Swiss Alps from 16-20 March 2026 and will be hosted by SKACH - the Swiss Consortium to the SKAO.
ASTRONAUT CLAUDE NICOLLIER ATTENDING OUR WELCOME DINNER
We will also have the honor to host Astronaut Claude Nicollier who will give a welcome address during our Welcome Dinner on Monday 16th March 2026. Furthermore, Les Diablerets is very special to him as it is the home of the Nicollier family. For more information on Claude Nicollier, please click here.
ABSTRACTS AND REGISTRATION INFORMATION
Abstracts will be open from 10 September to 30 October 2025. For registration, please go to the "Registration Information" section on the menu window.
We look forward to welcoming you to Switzerland!
