We are hosting the workshop “After the Avalanche: Astrophysical Lessons from the Fourth GW Observing Run” from 22 to 26 February 2027 at the Sexten Center for Astrophysics in Sexten/Sesto, Italy (www.sexten-cfa.eu).
Taking place just a few weeks after the planned full O4 data release, the workshop will be a timely opportunity to discuss the wealth of new results from the expanded gravitational-wave catalogue. We will bring together researchers working on astrophysical theory and modelling, numerical relativity, and gravitational-wave data analysis to explore what the properties of the observed population can tell us about the formation and evolution of merging compact objects and the astrophysical environments in which they originate. We aim to create a collaborative and discussion-focused setting in which participants can present their latest results, connect observations with theoretical predictions, and identify exciting directions for future work.
The core programme will take place at Haus Sexten, located in the centre of Sexten/Sesto, a scenic mountain village in the Dolomite Alps. Shuttle buses between Venice Airport and Sexten/Sesto will operate on 21, 26, and 27 February. Alternatively, the venue can be reached by regional public transport via Innichen/San Candido railway station, followed by a short bus ride to Sexten/Sesto.
Sexten/Sesto lies at the heart of the renowned 3 Zinnen Dolomites winter sports region and the UNESCO World Heritage-listed Dolomites. There will be plenty of opportunities to continue discussions with your colleagues on the downhill or cross-country ski trails, or during walks and winter hikes around the village. The conference fee will be EUR 300 and EUR 60 for a conference dinner.
We are looking forward to welcoming you in Sexten/Sesto in February and would be grateful if you could share the announcement with members of your research group -particularly early-career researchers – and other colleagues who might be interested.
Registration will remain open until 8 November 2026 via the workshop webpage: https://www.sexten-cfa.eu/event/after-the-avalanche-astrophysical-lessons-from-the-fourth-gw-observing-run
