NEHOP 2027 – New Horizons on Primordial Black Hole Physics, June 14-18, 2027 at University of Patras

After four very successful editions in Naples, Edinburgh, Brussels and CERN we are delighted to announce the fifth New Horizons in Primordial Black Hole Physics (NEHOP'27) workshop. This year, it will take place in the beautiful city of Patras, Greece, from 14th to 18th of June, 2027.

This workshop event aims to nurture discussions and bring together experts on the broad topic of Primordial Black Holes (PBHs). From their phenomenological implications, their possible relationship to extant problems in the SM (dark matter, neutrino masses, baryon asymmetry, inflation), their theoretical underpinnings and origin, to the multi-messenger signals that are motivating state-of-the-art experimental developments.

While most talks will consist of short, technical presentations by young researchers, a small number of expert talks will be included to both provide comprehensive overviews and present new results on key topics.

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.

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.
