In 2016, a short time before the announcement of the first gravitational-wave detection, a cross-disciplinary initiative in Europe led to the establishment of the new CA16104 COST networking Action on "Black holes, gravitational waves and fundamental physics'' ("GWverse''). GWverse aims to maintain and consolidate leadership in black-hole physics and gravitational-wave science. The Action supports the training of the next generation of leaders in the field, and the very first "native'' GW/multi-messenger astronomers, ready to tackle the challenges of high-precision GW astronomy with ground and space-based detectors.
The Action has been a tremendous success, contributing to the establishing a tight and young community across Europe. The last global meeting is to be held in Lisbon, Aug 30 - Sept 03.
