Dear colleagues,

The fourth installment of the two-week workshop “New frontiers in strong gravity” will take place in Benasque, Spain, from 19-31 July 2026. The registration is now open at the website https://benasque.org/2026relativity/%C2%A0where you can find further information.

The goal of the workshop is to foster new ideas and collaborations by bringing together experts across different disciplines, including gravity, gravitational wave astrophysics, numerical and mathematical relativity. We plan for only two talks per day, with ample time for informal discussions, sessions and collaborations. We aim at creating a diverse and inclusive meeting that thrives through communication and discussion, and we would greatly welcome participation and contributions from different communities, as well as researchers at different career stages.

Invited speakers include: Josu Aurrekoetzea - Miguel Bezares - Marina de Amicis - Elena Georgi - Archisman Ghosh - Ruth Gregory - Kelly Holley-Bockelmann - Alex Jenkins - Elisa Maggio - Simone Mastrogiovanni - Julio Parra-Martinez - Rafael Porto - B. Sathyaprakash - Thomas Sotiriou - Leonard Susskind - Rodrigo Vicente - Nils Vu - Silke Weinfurtner - Sebastian Zell

We look forward to welcoming you to Benasque,

Helvi
