Ringdown in Lisbon, October 19-21 2026

Ringdown-focussed workshops have been held in New York in February 2022 and in Copenhagen in August 2024. For the growing community of people working on this topic, we plan to have the next meeting in 2026.

In the last year, the realm of black hole quasi-normal modes have been more vibrant than ever. The large number of updates is recognisable in the rise of a vibrant, young and motivated community that is pushing the boundaries of where we can test the nature of black holes with gravitational waves observations. The aim of this workshop is to give a space to this community for relaxed discussion session and fostering the birth of collaborations.

If you want to participate to the workshop, please fill in the registration form. Please be aware that the maximum number of partecipants is 100 and priority is given to invited participants. You will need manual confirmation from the organisers to finalise the registration.

Gravitational Waves at the Fin del Mundo, January 11-22 2027, Universidad Central La Serena

Since the historic first detection in September 2015, gravitational wave observations have become routine, with the LIGO-Virgo-KAGRA network now detecting approximately one black hole merger every three days and having captured around 300 events to date. The future promises even more: next-generation detectors like the Einstein Telescope and Cosmic Explorer are expected to detect hundreds of thousands to millions of compact binary coalescences per year. These observations enable tests of fundamental physics in strong-gravity regimes, insights into the nature of compact objects and the evolution of stars, probes of cosmological evolution, and opens the possibility of multi-messenger astrophysics.

Join us for the 4th Gravitational Wave School in Chile (January 11-15), continuing a proud tradition of training a new generation of latin-american scientists in this growing and exciting research field. This time, the event will be followed by the international conference Gravitational Waves at the Fin del Mundo (January 18-22), inviting world-leading experts in strong-field gravitational physics and astrophysics.

These events will be held at Universidad Central in La Serena, Chile. La Serena is a charming seaside, in a region renowned for its pisco production and tropical papayas. Most importantly, La Serena serves as the gateway to some of the world’s most important astronomical facilities, including Vera C. Rubin Observatory, Cerro Tololo, Gemini, Las Campanas, and La Silla—making it the perfect location to explore the future of gravitational wave astrophysics.

Asian Gravitational Wave Astronomy Meeting 2026 (AGWAM-2026), July 5-11 in Chiang-Mai, Thailand

The Asian Gravitational Wave Astronomy Meeting (AGWAM) 2026 will be held on July 5–11, 2026, at the National Astronomical Research Institute of Thailand (NARIT) in Chiang Mai, Thailand. This meeting aims to bring together students, early-career researchers, and experts across Asia and beyond to discuss recent developments in gravitational-wave (GW) astronomy, astrophysics, cosmology, and fundamental physics.  This meeting follows the successful APCTP-GW2025 program held at Academia Sinica, Taipei.

AGWAM-2026 is structured as an integrated six-day program with two complementary components, organised on alternating days to maximise interaction between early-career researchers (ECRs), students, and experts throughout the week.

The first component is a three-day student school, designed to provide a broad and accessible introduction to GW science. It will feature pedagogical lectures by leading experts and hands-on sessions covering key aspects of GW data analysis and observational techniques, such as pulsar timing.

The second component is a three-day technical workshop, focusing on current research topics and recent advances in the field.  It will include invited talks, contributed presentations, and open discussions, with a strong emphasis on fostering participation by ECRs. 

By alternating school days and workshop days, the program ensures that students and ECRs can engage closely with experts over the full week, moving seamlessly from foundational learning to cutting-edge research discussions.

The scientific program will cover a broad range of topics, including:

  • Pulsar Timing Arrays (PTAs) & Their Transformative Sciences
  • Current and future  ground-based GW observatories & Their Precision Sciences
  • Space-based GW missions  & Their Discovery-Driven Sciences
  • Early-Universe Probes  & Their Foundational Sciences
  • Data Analysis, Signal Processing  & Their Computational Sciences

Students and early-career researchers are especially encouraged to participate. The meeting will provide an inclusive platform for learning, discussion, and networking with established leaders in the field. 

A dedicated open forum will address the theme of strengthening multi-band and multi-messenger GW astronomy in the Asia-Pacific region, with the explicit goal of identifying collaborative opportunities and establishing long-term scientific priorities.

Contributed talks and posters are welcome; however, presentation slots are limited.

Deadline for registration and abstract submission: May 15, 2026

Support for attending the meeting will be available to deserving participants.

Light refreshments will be provided during breaks. Participants will be responsible for their own meals. A conference banquet will be organised during the week.
