In Pursuit of Gravitational Waves: Solving the Two-Body Problem in General Relativity, Potsdam, October 20-22, 2025

The year 2025 offers a fitting moment to reflect on the development of one of the most profound problems in general relativity: the relativistic two-body problem. Just over fifty years ago, the discovery of the Hulse–Taylor pulsar provided the first observational evidence for gravitational radiation from binary systems. Since then, key contributions have marked decisive steps forward, leading to the first detection of gravitational waves in 2015 by the LIGO-VIRGO collaboration. As we commemorate ten years since that historic achievement, this progression of achievements not only traces a remarkable trajectory of scientific progress but also underscores the crucial interplay between analytical, numerical, and experimental communities in advancing our understanding of the two-body problem and its foundational role in gravitational-wave astronomy.

Against this backdrop, the Balzan Workshop In Pursuit of Gravitational Waves: Solving the Two-Body Problem in General Relativity, to be held from October 20 to 22, 2025, will bring together a select group of researchers who have played a central role in this history, alongside historians and philosophers of physics. The workshop offers an opportunity not only to revisit landmark developments, but also to reflect on the evolving methods, collaborations, and conceptual challenges that have shaped this remarkable scientific journey.

Hosted by the “Astrophysical and Cosmological Relativity” division at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Potsdam, Germany, the Workshop is part of the Balzan Prize Project. This project investigates the historical and philosophical dimensions of solving the two-body problem in general relativity, with particular emphasis on the development of both analytical and numerical approaches, as well as the synergy—and at times, the dissonance—between these methods. The event will feature twelve talks that are historical, philosophical, and forward-looking in scope, along with three panel discussions centered on key themes:

• Why Did Progress in Analytical Relativity Differ in Europe Compared to the US, and More Generally Among Countries?
• Why Did the Progress in Numerical Relativity Differ in Europe Compared to the US, and More Generally Among Countries?
• Appreciation, Competition, and Synergism Between Analytical and Numerical Relativity Approaches

Contributions from experimentalists are also included, highlighting how theoretical modeling has both informed and responded to observational work.

The workshop is by invitation only. Each talk will be complemented by ample time for discussion, encouraging open and engaging exchanges across disciplinary boundaries.

GW-EM-Nu-2025: Multi-Messenger Science With Indian Facilities-Now and in the Next Decade, December 1-3 2025 at Tata Institute of Fundamental Research

This year marks the 10-years of discovery of Gravitational Waves, which has opened a new window for multi-messenger science. The era of multi-messenger science using signals from astrophysical sources observed in different cosmic messengers such as Cosmic Rays (CRs), Electromagnetic Waves (EW), Gravitational Waves (GW), and Neutrinos opens a new paradigm in understanding the physics governing the Universe over different length scales from the size of a nucleus to the size of the observable Universe. The success of this research frontier relies on the coordinated observation between different existing telescopes/observatories which are observing in different messengers and also on building the next generation telescopes/observatories that can jointly observe signals using different cosmic messengers in the coming years in the frequency range (or energy band) which are of scientific interests based on our theoretical understanding of these astrophysical sources.

This conference plans to bring researchers from India working in different areas–instrumentation and theory on the same platform to discuss (i) the requirements and challenges in coordinated observations with existing Indian facilities between different messengers, (ii) key areas of development of telescope facilities and theoretical predictions for enhancing the scientific outcome, (iii) the roadmap for joint observations using multiple telescopes, and (iv) plan for strategically important future telescopes/observatories which will enhance multi-messenger science from India.

Capra 29 in Brussels, June 26 – July 3, 2026

We are pleased to announce that the 29th Capra Meeting on Radiation Reaction in General Relativity will be hosted in Brussels from Monday June 29th to July 3rd 2026. It will take place as a Solvay workshop organised by the International Solvay Institutes.

Further information about Capra 2026 will be posted in the coming months on https://www.caprameeting.org/ and https://solvayinstitutes.be/home/activities/workshop/ .

The Capra meeting is an annual conference on the topic of radiation reaction in general relativity. The primary focus of these conferences is the development of the gravitational self-force approach to model extreme mass ratio inspirals and further our understanding of the two-body problem in general relativity. This is done in synergy with other well-known modeling techniques such as post-Newtonian theory and numerical relativity. The canonical example of an extreme-mass-ratio inspiral (EMRI) is the inspiral of a stellar-mass compact object into a supermassive black hole. Gravitational waves from these systems are a promising target for the future space-based detector LISA.

The study of radiation reaction and self-force is not limited to EMRIs, and a range of topics and applications to other areas of gravitational physics have been discussed at past Capra meetings; an example is the scattering of massive particles, which is currently an active area of research. The format of the meeting is an amalgamation of a daily invited review talk, short contributed talks and organised discussion sessions.

Following the tradition of past Capra meetings, no registration fee is charged. A contribution of 50 euros to the banquet will be requested at registration for the attendees that would like to join the banquet. Several selected early career researchers will be funded by providing up to 6 nights of accommodation during the conference. Applications will be reviewed by members of the local organising committee and the equity, diversity and inclusion team at Capra.
