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.

Save the Date: Black Holes Inside and Out 2027 (BHIO27): August 23-27 2027

The conference Black Holes Inside and Out 2027 (BHIO27) will take place at Sapienza University of Rome from August 23 to August 27, 2027.

This event follows the highly successful 2024 edition [https://strong-gr.com/black-holes-inside-and-out/], which brought together leading experts in black hole physics, including astrophysics and observational astronomy, cosmology, data analysis, mathematical and numerical relativity, perturbation theory, and quantum gravity, to discuss the state of the field and its future directions.

Preparations for the 2027 edition are underway, so please save the date! A webpage with all relevant information is under development and will be announced in early 2026.

We would greatly value your input regarding potential topics and speakers for this edition. To contribute suggestions, please fill out the following form: https://forms.gle/po4h8ifWm3LhvyTs7.

We particularly encourage suggestions outside your main areas of expertise, especially if motivated by an interest in learning more about developments in other branches of black hole physics.

Further information about the conference will be shared in the coming months.

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.

14th Cosmic-Ray International Studies and Multi-messenger Astroparticle Conference, July 13-17 2026, Sorrento

The 14th CRIS-MAC Conference will be held in Sorrento from 13 to 17 July 2026.

The Conference is jointly organized by the Department of Physics and Astronomy “E. Majorana” of the University of Catania, and by the Department of Physics and Chemistry “E. Segrè” of the University of Palermo and the Department of Physics “E. Pancini” of the University of Napoli Federico II and by the Catania and Napoli Divisions of the National Institute of Nuclear Physics (INFN).

As in previous CRIS editions, the conference will focus on fundamental topics in astroparticle physics with special emphasis on the multi-messenger astronomy studies. For this reason the conference acronym has been changed to CRIS-MAC (Cosmic-Ray International Studies and Multi-messenger Astroparticle Conference) while retaining the old CRIS series numbering.
The main focus of the CRIS-MAC conference is the multi messenger aspects of astroparticle physics which naturally includes fields such as cosmic-ray physics, gamma-ray and multi-wavelength astronomy, astrophysical neutrinos and gravitational waves.

The program includes invited lectures, contributed talks, posters and flash talks.

As in the past, the CRIS-MAC 2026 is addressed to scientists in the field as well as to PhD and graduate students. We will encourage lively and informal discussions among participants.
