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.

LISA Consortium kick-off meeting June 26

With the adoption of the LISA mission by the European Space Agency, the scientific community is organizing itself into a revitalized LISA Consortium. To celebrate this transition and to begin organizing the scientific and engineering community around the exciting work needed to bring LISA to fruition, you are warmly invited to an online kick-off meeting that aims to bring together long-time LISA community members and people new to the LISA effort.

The evolved LISA Consortium kick-off meeting will be on June 26 at UTC 13:00-16:00 via zoom (the link will be available about a week before the meeting).

The meeting is open to all interested people regardless of consortium membership status and aims to share the evolution of the consortium structure and membership with brief presentations from the working groups. It will also present the wider LISA landscape, status of the mission, new consortium governance, and interaction with ESA, NASA, and the LISA Science Team. There will be ample time for Q&A.

SN2025gw: First IGWN Symposium on Core Collapse Supernova Gravitational Wave Theory and Detection, July 21-25 2025, Warsaw

The LIGO–Virgo–KAGRA Collaboration invites the core-collapse supernova (CCSN) astronomy and astrophysics community for a 5-day Symposium on July 21–25, 2025, at the University of Warsaw, Poland. CCSNe are among the most violent explosions known to occur in the Universe, and the next Galactic or near-extra-Galactic exploding massive star will be one of the most interesting, and most important, astronomical events of the century. This Symposium aims to bring CCSN experts together to address how to maximize the scientific potential of the first detection of core collapse supernova gravitational waves (GWs). The Symposium hopes to bring together GW astronomers and CCSN modelers, as well as neutrino and nuclear theorists, neutrino astronomers, and astronomers across the electromagnetic spectrum.

The sensitivity of GW detectors and progress on CCSN modeling are unprecedented, and we expect them to further advance in the coming years. A joint effort across communities has great potential to fully utilize these advances for CCSN GW discovery. Each day, we will host (before lunch) a set of lectures on one of the key topics listed below, to establish a common understanding and a common language. Moreover, each day (after lunch) will also include invited and contributed talks, as well as discussion. The focus topics of the Symposium are:

Day 1: CCSN Theory
Day 2: CCSN Gravitational Wave Detection and Parameter Estimation
Day 3: CCSN Neutrino Detection
Day 4: CCSNe across the Electromagnetic Spectrum
Day 5: CCSNe over the Next Ten Years

The proceedings of the Symposium will be published in a special issue of Classical and Quantum Gravity. We hope the proceedings will serve as a reference for students, postdocs, and faculty in, or entering, the field, serve to capture the current state of core collapse supernova gravitational wave astronomy and astrophysics, outline lessons learned, and provide recommendations for future development.

Everyone who wishes to advance the field of CCSN GW science is welcome!
