This year, the 14th edition of the Belgian-Dutch Gravitational Wave Meeting will take place at UCLouvain, from the 7th to the 9th of October 2026. The aim of the meeting is to bring together people in our communities involved in gravitational wave science at large, ranging from instrumentation, to astronomy, to theory, and data analysis. This year, we propose a slightly longer duration to allow for more time to discuss various aspects in informal settings, in addition to offering room for presentation across all topics.
Both plenary and parallel sessions will take place at the Aula Magna.
