Ripples Through Time: Past Triumphs, Mapping the Future, November 25-27, 2026 at UWA Perth

Celebrating 50 years of gravitational wave research, science education, and future innovation

A century ago gravitational wave detection was thought to be impossible. Fifty years ago it was the quest of a small bunch of intrepid physicists. They faced challenge after challenge, but their optimism persisted. They uncovered new physics, invented novel instruments and new techniques. New disciplines like quantum optomechanics, space laser communication, clock technology and airborne exploration technologies emerged from their efforts. Year after year they overcame setbacks, never imagining that it would take 40 years of struggle to achieve their quest.

When the direct detection of gravitational waves was finally achieved in 2015, it marked the beginning of a new era in astronomy. It brought with it surprises and opportunities, new horizons and new questions. Today, thousands of researchers all over the world work together, using increasingly sensitive detectors to explore the universe in ways that were once unimaginable.

This symposium marks fifty years since Australia became part of the international quest to detect gravitational waves. Celebrating the remarkable achievements of gravitational wave researchers, it aims to inspire the next generation of scientists, map the future, and identify opportunities. What are the greatest challenges, what might we discover and what is the future of physics?

The symposium is held in honour of David Blair, commemorating his 80th birthday and recognising his extraordinary 50 years of contributions to physics, physics education and public awareness of science.

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.

Iberian GW Meeting and International School on GWs 2026, Apr 26 – May 02, Benasque

The Iberian Gravitational Wave Meetings (IGWM) are annual meetings organized by the REDONGRA community which have played a key role in establishing a Spanish GW community, and in integrating new groups.

We organize these meetings with focus on specific joint R&D activities, in particular toward maximizing the Spanish role in the breakthrough discoveries expected in the next few years (the LIGO-Virgo-KAGRA detections and the new Pulsar Timing Array data), and in developing the future Einstein Telescope (ET) and LISA (Laser Interferometer Space Antenna) observatories.

In the context of the new REDONGRA funded network, we add the International School on Gravitational Wave Physics (ISGWP), which will consist of a series of lectures and hands-on sessions covering all relevant aspects of GW science (instrumentation, simulations, data analysis algorithms, theory), to be delivered by internationally recognized experts. We profit from the joint organization of the IGWM and ISGWP by the presence of these experts in both events. The ISGWP will be mainly addressed to PhD students and young postdocs, with the aim of training the next generations of GW scientists.
International School of Gravitational Wave Physics (ISGWP)
‘Simulations and Data Exploitation in Gravitational Wave Astronomy’

The School (ISGWP-2026) will take place form April 27 to April 29, 2026.
It is primarily aimed at graduate students and early-career researchers, although participation is open to all interested scientists.

The school will consists of six lecture courses of three hours each, covering the following subjects:

  • Tools of Bayesian Inference in Gravitational Wave Astronomy
  • Simulations and Waveform Models for Compact Binary Coalescences
  • Basics of Searches of Compact Binary Coalescence Events
  • Simulations and Data Analysis for Supernovae and other Burst Events
  • Basic Elements of Data Analysis for LISA
  • Simulation Based Inference in Gravitational Wave Astronomy

Iberian Gravitational Wave Meeting 2026 (IGWM 2026)

The Iberian Gravitational Waves Meeting (IGWM-2026) will take place from April 30 to May 2, 2026.
This annual meeting has been organized since 2011 and brings together researchers interested in all aspects of Gravitational Wave Astronomy.
It plays an important role in consolidating the gravitational-wave community in Spain and Portugal and is supported by the REDONGRA network.

The meeting will feature invited and contributed talks on current developments in gravitational-wave physics, promoting interaction within the Iberian community while strengthening connections with international collaborations.

APPEC Town Meeting Geneva 2026, September 2-3

Dedicated to the preparation of the 
European Astroparticle Physics Strategy 2027–2036
The meeting will take place in person in Geneva, Switzerland, on 2–3 September 2026.
**Registrations will open in the coming weeks**

As part of the roadmap development process, a community-wide survey was conducted in 2024 within the astroparticle physics community, followed more recently by a second survey across European astroparticle physics collaborations. Drawing on these valuable inputs, the APPEC Scientific Advisory Committee is preparing a draft Roadmap addressing all strategic themes identified in the surveys, with a preliminary version expected in summer 2026.

This Town Meeting will provide an opportunity to examine each scientific topic in depth, considering both the European and the broader international context. We will discuss recent advances in astroparticle physics and neighbouring disciplines, as well as developments in the research infrastructures landscape — all of which will contribute to shaping the strategic recommendations for the coming decade.

Over the course of two days, the programme will combine plenary presentations with focused round-table discussions. This format is designed to foster broad community engagement and to ensure that participants play a central role in defining the future strategic directions of astroparticle physics in Europe.

The discussions and conclusions from this 2nd Town Meeting will serve as the final community input to the European Astroparticle Physics Strategy 2027–2036.
