AI for Gravitational Waves at CERN, May 5–8, 2026 at CERN

As gravitational-wave (GW) observatories enter an era of rapidly increasing detector sensitivity, bandwidth, and data rates—while the machine-learning (ML) ecosystem continues to mature—there is a timely opportunity to bring together the GW and AI communities in a focused setting at CERN.

This workshop will convene researchers from the LIGO–Virgo–KAGRA (LVK) collaboration, the Einstein Telescope (ET), LISA, and the broader CERN AI community to (i) share recent advances, (ii) identify common technical challenges across experiments, and (iii) seed new cross-disciplinary collaborations—especially those relevant to next-generation detectors and real-time analysis. A dedicated focus will be placed on real-time data processing and next-generation triggers, highlighting synergies between GW low-latency pipelines and high-energy physics trigger/DAQ developments.

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)

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.

Balzan Conference on Open Issues in Gravitation, March 24-26, 2026 at IHES

The Balzan Conference on Open Issues in Gravitation is part of the research project carried out at IHES with the 2021 Balzan Prize for Gravitation: Physical and Astrophysical Aspects, awarded to T. Damour.

This three-day conference will bring together leading experts in a wide range of topics related to gravitation. Besides offering an overview of the status of the field, the talks will address open issues in gravitation that are currently the focus of intense research, such as: gravitational waves, tests of General Relativity, numerical relativity, self-force, new approaches to Black Hole perturbations, extreme black holes, BMS, post-Minkowskian gravity, scattering amplitudes, high-energy scattering, effective field theory, etc.

The talks will be videotaped, thereby completing the collection of Balzan Lectures at IHES (available on carmin.tv)

Gravity & Cosmology: Searching for Concordance – 6th EPS Conference on Gravitation, June 1-3, 2026 in Stavanger

Gravity impacts all stages of the evolution of the universe, but the precise role of fundamental gravity in modeling cosmology remains to be understood. Current cosmological tensions may be related to an incomplete or oversimplified treatment of gravity and spacetime in the ΛCDM model, and highlight the need for quantifying the influence of initial conditions, local effects of gravity and backreaction beyond a perturbative analysis on FLRW backgrounds.

Recent advances in numerical and analytical methods and a wealth of astrophysical precision data allow for new, systematic studies of the interplay of matter, geometry and inflationary expansion, and open new pathways for a model-independent analysis. Research that exploits the interwovenness of gravity and cosmology includes the proposed use of gravitational wave observations to elucidate the extreme physics of the early universe, and of cosmological probes to constrain modified gravity theories. The big underlying challenge – besides unraveling the complexities of the history of our universe and the nature of its initial big-bang singularity – is to come up with clear evidence for new (quantum) physics beyond general relativity and the standard model of particle physics.

Gravity & Cosmology: Searching for Concordance brings together researchers working on different aspects of the cosmology-gravity interface, who may not necessarily meet at more specialized, subcommunity-oriented events, to exchange views on what are the most feasible and promising ways forward and explore how they relate to each other. Our keynote speakers are leading experts on numerical and mathematical relativity, modified gravity, quantum cosmology, cosmography, gravitational wave cosmology, cosmological tensions, backreaction and phase transitions, and on foundational aspects. We aim for an interactive meeting and for constructive and respectful dialogue, including organized discussions on future challenges and opportunities. We invite the submission of abstracts for contributed talks and posters and encourage especially junior researcher to participate.
