2027 Summer School on Gravitational Waves, Les Houches, July 5-30, 2027 We are pleased to announce that the 2027 session of the MaNiTou summer school on gravitational waves will be at the Les Houches School of Physics (Les Houches, France) in 2027. This will be a month long summer school, from July 5 to July 30. So please mark your schedules. Application and registration information will be coming soon.

Quantum Gravity 2027, September 13-17 at Heidelberg University Quantum Gravity 2027 is the fourth installment in a series of international conferences that are based on the premise that a constructive and collaborative dialogue between distinct approaches can boost research in quantum gravity. Based on this premise, the conference will highlight recent developments as well as long-standing research lines and will enable fruitful interactions between different perspectives on quantum gravity.

61st Rencontres de Moriond March 14-21, 2027 in La Thuile 61st Rencontres de Moriond will host its Gravitation session in La Thuile, a ski resort in the Italian Alps, from March 14 to 21, 2027. Registration is now open and closes on January 27, 2027. A limited number of grants is available to support young scientists who do not receive funding from their institutions. Conference Website

The School on Gravity: From Commotion to Locomotion, June 21-25 2027 at NBI Copenhagen The School on Gravity (21–25 June 2027, Copenhagen) will introduce junior scientists—graduate students and advanced undergraduates with a background in general relativity—to a wide range of foundational topics in the exciting new field of gravitational wave physics. Topics will span from the theory of motion, to new challenges introduced by quantum physics, to the astrophysics of black holes and source modeling for gravitational-wave detectors. School Website

LISA Spain Meeting 2026, November 11-12 at IAC3 in Palma This is the third (first in Barcelona 2024, second in Madrid 2025) in a series of meetings devoted to the organisation and scientific collaboration of Spain-based researchers working or interested in the LISA mission. Meeting Website

GW170817: 10 Years Later – August 16-20, 2027 The five-day program covers gravitational-wave detection and sky localization; radio, X-ray, and optical astronomy; modeling and data analysis; and nuclear astrophysics. Rather than confining each theme to its own day, each day combines observational, modeling, and nuclear-physics perspectives. Every day opens with a keynote from a leader in the field, followed by invited talks and short contributed talks, with priority given to early-career speakers for contributed slots.

Madrid Winter Workshop on Gravitational Physics 2026, December 14-16 The Madrid Winter Workshop on Gravitational Physics 2026 (MWWGP-2026) is the seventh in a series of Workshops intended to bring together researchers with common interests on the geometric structure of space-time, quantum properties of gravity, modified theories of gravity, cosmology, and astrophysics, and who collaborate or can potentially collaborate among each other via active projects. It will take place on December 14-16th, 2026. This workshop oscillates between Valencia and Madrid, this time being hosted by the Departament of Theoretical Physics and the Instituto de Particulas y Fisica del Cosmos (IPARCOS) of the Complutense University of Madrid, Spain.

IAU Webinar Series, October 29–30 2026: Gravitational-Wave Astrophysics & Multimessenger Astronomy Two global sessions bringing together early-career researchers across gravitational-wave astrophysics — from compact-object populations and pulsar timing to LISA, strong lensing and multimessenger science. Webinar Website & sign-up

International LILA Meeting – 2026 Lunar GW Workshop, December 2-4 in Pisa This meeting continues community discussions on the Laser Interferometer Lunar Antenna (LILA) project – a proposed detector on the lunar surface to measure gravitational waves in the mid-band between ground-based detectors LIGO–Virgo–KAGRA and the future space mission LISA. The 2026 workshop will focus on defining LILA’s science goals, instrument architecture, and deployment timeline, while expanding and strengthening the global LILA community. Meeting Website
