Cosmological Fundamental Observables and Novel Discoveries in Universe Evolution, January 25-29, 2027 at CERN

hile new discoveries in cosmology have revolutionized our understanding of the Universe over the past decades, many unresolved mysteries remain, such as the nature of dark energy or the physical processes occurring in the earliest stages of history. To resolve these questions in light of new observations, joint efforts across the whole community are needed.

The conference Cosmological Fundamental Observables and Novel Discoveries in Universe Evolution (CosmoFONDUE) aims at offering an occasion for scientists across all fields of cosmology to interact in an engaging and inclusive atmosphere, and to reflect on promising new research directions. A special focus is put on fostering exchange among junior and senior researchers. The conference will cover a broad range of topics across the full redshift span, including:

  • Inflation, pre-CMB cosmology
  • CMB surveys
  • Neutrino & particle cosmology

IGWN School at Perimeter Institute, August 10-14, 2026

The IGWN School will be held August 10 - August 14, 2026 at Perimeter Institute. 

The International Gravitational Wave Network (IGWN) School is an intensive one-week program designed for graduate students and early-career researchers seeking to contribute to gravitational wave astronomy through engagement with the global LIGO–Virgo–KAGRA collaboration. The school will offer a comprehensive introduction to the science, infrastructure, techniques, and collaborative practices that underpin modern gravitational-wave astronomy given by leading scientists from across this international network of advanced gravitational-wave detectors. Participants will explore the many aspects of gravitational wave observations—from detector operations and characterization to data analysis and astrophysical interpretation—gaining the practical knowledge and methodological tools needed to contribute effectively to this large, worldwide scientific effort. Through lectures, tutorials, and interactive sessions, this program aims to foster a new generation of researchers capable of actively participating in a global collaboration of thousands of scientists working together to make groundbreaking discoveries.

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.

The RING project in Germany: 1 Postdoc and 14 PhD positions in Physics, Geophysics, Geodesy

we would like to draw your attention to the 4-year RING project recently funded by the German Research Foundation (extendable to 8 years). The project has strong overlap with gravitational wave detection research on instrumentation.

The project aims at pushing the sensitivity and stability limits of rotational motion sensing with ring laser technology into new realms using approaches from quantum optics and metrology. The ultimate goal is to enable ring laser observations as a complement to classic space-geodetic methods towards more precise, high-rate estimation of Earth Orientation Parameters (EOP). Furthermore, we plan to develop (trans-) portable ring lasers fit for weak, broadband 6 degree-of-freedom ground motion observations towards better understanding of atmosphere-solid Earth coupling (also relevant for seismic decoupling of gravitational wave detection facilities).

The project offers postdoctoral and PhD topics in laser physics, geodesy, geophysics, hydrology, and seismology. The successful candidates will be part of a multi-disciplinary research team at various institutions in Germany with excellent training and experimental facilities.

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.

GRAVITY@PRAGUE 2026, September 14-18 in Prague

This school will feature a set of advanced lecture courses around the theme of gravity given by experts in the field. The courses will be aimed at advanced graduate students and young postdocs with a strong interest in the theoretical aspect of gravity and applications of the theory to modelling the universe.

The school is co-organised by CEICO, a centre in the Institute of Physics of the Czech Academy of Sciences for research in cosmology, gravity and fundamental physics and the Faculty of Mathematics and Physics of Charles University in Prague. We are bringing together excellent lecturers from the global community and hope to foster a diverse audience. There will be limited space for the presentation of a poster, but no submitted talks by participants are planned.

There is no registration fee, and participants should arrange their own accommodation (see Venue).
