Multi-Messenger Astrophysics in the Dynamic Universe, January 26 – February 27, 2026 at YITP Kyoto University Astrophysics has finally entered a new era, transitioning from the multi-wavelength observation approach of the 20th century to the era of multi-messenger observations. The discovery of the binary neutron star merger event GW170817 in 2017 marked the beginning of this shift, as it was first detected through a gravitational wave and gamma-ray burst, followed by electromagnetic counterparts observed across various wavelengths, including X-ray, optical, infrared, and radio. In addition to gravitational waves, significant advancements have also been made in other multi-messenger signals, such as high-energy neutrinos and high-energy gamma rays. Traditional X-ray, optical, infrared,…

3rd TVLBAI Workshop, August 20-22, 2025 in Hannover The 3rd Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) workshop follows the formation of the TVLBAI Proto-Collaboration and will focus on discussing the technology and physics drivers for large-scale Atom Interferometry as well as establishing a comprehensive roadmap. The primary objectives are to bring together researchers from diverse institutions and communities, foster strategic discussions, and develop a pathway towards Funding for Terrestrial Very-Long Baseline Atom Interferometer projects expected to become operational in the mid-2030s.

Summer School on String Theory and Summer School on Gravitational Waves, July 31 – August 10, 2025 On the theory and phenomenology tracks of PSI, we are organizing two schools in parallel—one on String Theory and the other on Gravitational Waves. School Website

First International Latin American Conference on Gravitational Waves: 10 years since first detection September 15–19 2025 at INPE Sao Paulo A decade ago, science witnessed an extraordinary milestone: the first direct detection of gravitational waves, predicted by Albert Einstein in his Theory of General Relativity in 1915. These ripples in spacetime, generated by extreme cosmic events such as black hole mergers, remained merely a theoretical prediction until September 14, 2015, when the LIGO (Laser Interferometer Gravitational-Wave Observatory) experiment captured this historic signal.

CoCoNuT Meeting, December 11-13, 2024 in Valencia The CoCoNuT Meeting is a series of workshops aiming at fostering collaboration among relativistic astrophysicsgroups, specially within Europe. The series has been taking place yearly since 2009 and this year is hosted by the University of Valencia. Meeting Website

DTP/TALENT 2024, Nuclear Theory for Astrophysics, July 15 – August 2 2024, Trento Nuclear physics and astrophysics are strongly linked through neutron stars, compact objects that represent the densest form of matter in the universe. Neutron stars also have strong synergies to nucleosynthesis and the origin of the heaviest elements in the cosmos. This TALENT school will cover: 1) the equation of state of neutron-rich matter and new constraints inferred from nuclear theory, experiment and observations, 2) core-collapse supernova as the birthplace of neutron stars, and 3) neutron star mergers and gravitational waves to probe the neutron-star interior.

First Stars VII, May 20-23, 2024, New York The „First Stars“ conference series has brought together astronomers and astrophysicists working on the high-redshift universe roughly every four years since 2007[*]. The seventh edition, First Stars VII, will be hosted in New York City by the Flatiron Institute 20-23 May 2024. The meeting will feature invited review talks, contributed talks and posters and will leave ample time for discussion. The scientific program will balance theory, observations, and numerical simulations. Conference Website
