Location:  Geneva, Switzerland

We are delighted to announce the workshop “Advancing Gravitational Wave Predictions from Cosmological First-Order Phase Transitions”, which will take place at CERN from August 25 to 29, 2025.

The program will focus on gravitational wave production during first-order phase transitions and aims to provide a comprehensive overview of the topic, covering analytical and numerical techniques to study the micro- and macrophysical dynamics, as well as their interface.

The format of the talks will be in-person, with a limited number of participants, but online participation is possible and unlimited.

Invited speakers: Andrii Dashko (DESY), Wen-Yuan Ai (U. Vienna), Jani Dahl (U. Helsinki), Oliver Gould (U. Nottingham), Ryusuke Jinno (U. Kobe), Lorenzo Giombi (U. Helsinki), Anna Kormu (U. Helsinki), Benoit Laurent (U. McGill), Mark Hindmarsh (U. Helsinki), Kari Rummukainen (U. Helsinki), Andrew J. Long (Rice U.), Tina Kahniashvili (U. Carnegie Mellon), Bogumila Swiezewska (U. Warsaw), Thomas Konstandin, (DESY), Marek Lewicki (U. Warsaw), Antonino S. Midiri (U. Geneva).

We are looking forward to welcoming you in Geneva!
The organizers: Chiara Caprini, Simona Procacci, Alberto Roper Pol, Philipp Schicho, and Jorinde van de Vis

Abstract:
As the detection of a stochastic gravitational wave (GW) background from the early universe becomes increasingly plausible, signals from hypothetical first-order phase transitions are attracting growing interest. Predicting these signals often requires microphysical inputs to solve hydrodynamics, along with various assumptions on distinctive scales and their separation to enable concrete evaluations. This workshop aims to unite researchers from both microphysical and macrophysical communities to collaboratively address theoretical shortcomings and refine current GW spectral templates across different regimes.
