CosmoFONDUE 2027, January 25-29 at CERN

While 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
  • Gravitational waves
  • Galaxy surveys, large-scale structure observables
  • Intensity mapping
  • Supernovae
  • Modified gravity
  • Cosmological tensions

Inside and Out – Black Holes III, August 23-27, 2027 at Sapienza University of Rome

Black Holes III will gather experts working on the many complementary aspects of classical and quantum black holes: their exterior geometry, their internal structure, their perturbations and stability, their formation and mergers, their observational signatures, and their possible extensions beyond General Relativity.
The meeting will take place at Sapienza University of Rome from 23 to 27 August 2027.

The gravitational-physics landscape has evolved rapidly, mostly driven by the possibility of studying strong-field regions and, in particular, black holes.

Black holes are among the most remarkable macroscopic objects in the universe. According to General Relativity, their exterior is extremely simple, while their interior points toward the limits of the classical theory. Understanding black holes therefore requires a broad effort, connecting gravitational theory, astrophysics, numerical relativity, quantum gravity, high-energy physics, and data analysis.

Multi-messenger lensing at Lorentz Center, October 19-23, 2026

We are happy to announce that registration is now open for the workshop "Gravitational Lensing in the era of Multi-Messenger Astronomy” taking place at the Lorentz Center, Leiden in October 19 - 23, 2026. Please register by September 6, 2026, with this form.

This workshop aims to catalyze the emerging field of multi-messenger gravitational lensing—a transformative approach to observing the distant Universe through the combined signals of gravitational waves, neutrinos, and electromagnetic messengers from gravitationally lensed transient events. The scientific motivation lies in the potential for such lensing events to unlock new insights into cataclysmic cosmic phenomena, from kilonovae, supernovae and gamma-ray bursts to binary neutron star mergers, offering a deeper understanding of astrophysics, cosmology, and fundamental physics. Through highly interactive sessions, the workshop will identify research priorities, foster coordination among facilities, and establish a roadmap for future work to enable the first detection of a gravitationally lensed multi-messenger event.

Confirmed participants include:

  • Nikki Arendse
  • Tessa Baker
  • Liang Dai
  • Daniel Holz
  • Andrew Levan
  • Matt Nicholl
  • Inés Pastor Marazuela
  • Antonia Rowlinson
  • Miguel Zumalacárregui

AG splinter session on Relativistic Astrophysics, September 11 2026, Garching, Germany

Splinter session about “Relativistic Astrophysics” as part of the annual meeting of the German Astronomical Society (Astronomische Gesellschaft, AG), hosted by the Max Planck Institute for Astrophyics from September 7 to 11, 2026, in Garching, Germany.

This session covers the observational and theoretical aspects of the physics in strong gravitational fields and of the emergence of high energy phenomena. Strong gravity and relativity will be important for the formation and nature of white dwarfs, Neutron Stars and Black Holes. Physical phenomena in the vicinity of compact objects are lensing and shadows, the motion of stars in strong gravitational fields, gravitational waves, accretion disks, jets, and Gamma-Ray-Bursts. Also the aspects of relativity in cosmology and dark matter search will be part of this session.

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.
