Cosmology at the Pati

Nov 16, 2026, 9:00 AM → Nov 20, 2026, 6:00 PM Europe/Andorra

Pati Manning and Institut d'Estudis Catalans (IEC), Barcelona

Fabrizio Rompineve (UAB & IFAE), Oriol Pujolas (IFAE; UAB), Stefan Stelzl (IFAE Barcelona)

This workshop aims to bring together international experts in particle physics and cosmology to discuss recent advances in our understanding of fundamental physics through observations of the Universe. The scientific program will focus on the interplay between theory and experiment, with particular emphasis on various probes of physics beyond the Standard Model such as early-Universe and late-Universe cosmological observations, gravitational waves, dark matter candidates, black holes.

The program will consist of a reduced number of talks leaving ample time for scientific discussion in the exceptional atmosphere provided by the Pati Manning (17-20 November), a peaceful retreat in the heart of Barcelona's vibrant Raval district. The opening day (16 Nov) will be held at the Institut d'Estudis Catalans.
